Command Changes
  - CLI SCRIPTMODE
This commands displays the CLI in Script Mode, which provides a 
  simple way to enter and test scripts.
   - Go FDBBUTTONS
The new Go 
  FDBBUTTONS command lets you add buttons to a toolbar that mimic the 
  standard File Display Border buttons. This command is designed to be 
  used on the new File Display Border toolbar as an alternative to the 
  standard 
  buttons.
            
     
                                        Standard 
  buttons                                                                            Toolbar 
  buttons
To use the command you would normally disable the 
  standard buttons using the options on the Preferences / File Display / 
  Border page, and then add the Go FDBBUTTONS command 
  with the desired arguments to the file display toolbar.
   - Go NEWTAB
The Go NEWTAB command 
  now supports embedded functions to run 
  a function in the context of the newly created tab.
   - Go WHENDUAL
This works in conjunction 
  BACK, FORWARD and UP and is 
  designed to be used with "app commands" like the Back button on a 
  mouse. Go BACK WHENDUAL=checkmouse in a dual display will 
  cause the command to act on the file display under the mouse pointer rather 
  than the source file display. Specifying the deffocus 
  argument as well will fall back to the old behaviour and act on the source if 
  the mouse pointer isn't over either file display.
  
   - Image LOCATE 
The Image 
  LOCATE command now supports Bing Maps (Image 
  LOCATE=bing) and Google Maps (Image 
  LOCATE=google) as well as Google Earth (Image 
  LOCATE=googleearth).
  
   - Properties SETLABELINFS
This new argument lets you 
  assign labels to files that are specifically stored in the file-system or in 
  your Opus configuration (overriding the setting in 
  Preferences).
   - Select FROMSCRIPT
The new Select 
  FROMSCRIPT command is used from a script to select files in the file 
  display. It lets you build a list of files using the script 
  Command object and then run the Select 
  command to select based on the files in that 
  object.
   - Set CALCFOLDERSIZES
The new Set 
  CALCFOLDERSIZES command can be used to change the state of 
  the Preferences / Folders / Folder Behaviour / Calculate folder sizes 
  automatically option.
  
   - Set DUAL
The Set DUAL command can 
  now combine the Toggle, Horiz / 
  Vert and ToggleLayout arguments, to create a button 
  that turns on dual-display mode in the desired orientation if it's not on, 
  switches the layout (from horizontal to vertical or vice versa) if 
  dual-display is already on but not in the desired orientation, and closes 
  dual-display mode it if it is on and already in the desired orientation. The 
  new buttons on the default Menu toolbar make use of this.
  
   - Set ENABLELABELFILTER
The new Set 
  ENABLELABELFILTER command allows label filters (wildcard and filter 
  based) to be turned on or off. You must assign a name to the label filter in 
  order to control it via the command line. Both global and Folder 
  Format-based filters are supported. You can specify 
  local:<name> and global:<name> 
  to restrict the type of filter you want to control, or just provide the name 
  and Opus will look for it in both types of filter.
  
   - Set FOCUS
The Set FOCUS command 
  now lets you assign the focus to the path field control (assuming there is one 
  on your toolbars). Set FOCUS=PathField will set the focus to 
  the source path field - in a dual-display Lister with dual path fields (i.e. 
  in the file display toolbar) you can also specify LeftPathField 
  and RightPathField.
  
   - Set LISTERTITLE
Added codes to Set 
  LISTERTITLE to get the left/right paths (as opposed to 
  source/destination paths):
    %1 - 
  left path
    %2 - right 
  path
    %3 - left folder 
  name
    %4 - right folder 
  name
  
   - Set SHOWMILLIS
The new Set 
  SHOWMILLIS command lets you toggle the display of milliseconds in 
  file time columns on or off. Note that seconds must also be displayed for this 
  command to have any effect.
  
   - Set SHOWSECONDS
The new Set 
  SHOWSECONDS command lets you toggle the display of seconds in file 
  time columns on or off.
  
   - Set SORTBY
The Set SORTBY command 
  can now automatically add the specified columns to the file display if 
  they're not already turned on (you can only sort by columns that are added to 
  the file display). To get this behavior, prefix the column name with a 
  + sign. For example, Set SORTBY=+datetaken 
  will turn on the Date Taken column if needed and then sort by 
  it.
  
   - Set STATUSBARSTYLE
The new Set 
  STATUSBARSTYLE command lets you control various status bar options, 
  and also test for them via @ifset. The keywords available for 
  this command are: 
  
    - Single - one single status bar 
    
 - Dual - one single status bar, with a separate 
    definition in dual-display mode 
    
 - Independent - separate status bars for left/right file 
    displays, with separate definitions for left and right 
    
 - IndependentSame - separate status bars for left/right 
    file displays, with the same definition for both 
    
 - Bottom - put the status bar(s) at the bottom of the 
    Lister 
    
 - NoBottom - put the status bar(s) at the bottom of the 
    file display(s) 
    
 - Glass - enable glass when the status bar is at the 
    bottom of the Lister 
    
 - NoGlass - disable glass
   
   - Toolbar APPBAR
When opening a floating toolbar, 
  specify this argument to dock the toolbar with the edge of the 
  screen.
  
   - Toolbar AUTOCLOSE
The new 
  AUTOCLOSE argument for the Toolbar command 
  can be used when opening a floating toolbar to make the toolbar close 
  automatically after running a command. This lets you have a toolbar that 
  can pop open (by keypress for example), run a command and close automatically 
  again, and saves having to add the Toolbar CLOSE=*this 
  command to all the buttons in the toolbar.
  
   - Toolbar CLOSE=all
This command can be used to 
  close all toolbars in the current Lister at once.
  
   - Toolbar FLOAT
The new FLOAT 
  argument lets you open a floating toolbar (equivalent to 
  STATE=float) with control over its appearance and 
  behaviour.
  
   - Toolbar LIST
The Toolbar LIST 
  command can now generate a dynamic list of toolbar 
  sets.
  
   - Toolbar LOADSET
This new command can be used to 
  load a toolbar set.
  
   - Toolbar LOCAL
Because toolbars are now local to 
  the Lister by default, the old LOCAL argument has no 
  effect (although it will not break compatibility with old commands). You can 
  now specify LOCAL=no to open or close toolbars in all 
  open Listers.
  
   - Toolbar POS
The POS argument for 
  the Toolbar command now works when opening docked toolbars 
  (appbars), and allows you to control which monitor the toolbar docks to 
  by specifying coordinates corresponding to that monitor. For example, if your 
  second monitor's coordinates start at 1920,0, specifying 
  POS=1920,0 APPBAR=bottom would dock the toolbar to the bottom 
  of the second monitor.
  
   - Toolbar SAVESET
This command can be used to save 
  the current toolbars as a set.
   - Toolbar STATE
The STATE argument 
  for the Toolbar command now lets you change which toolbar is 
  used for the file display border, by specifying STATE=fdb. 
  For example, Toolbar STATE=fdb TOGGLE "File Display" would 
  toggle the default file display toolbar on and off.
  
   - Toolbar SETDEFAULT
This command sets the current 
  toolbars as the Default Toolbar Set.
   - Toolbar UPDATE
Use the UPDATE 
  argument in conjunction with FLOAT and 
  POS to make changes to already-open floating 
  toolbars.
  
   - Undo LIST
The Undo LIST command 
  now accepts the optional arguments nokeys (to disable the 
  automatic hotkey for each item) and menu (makes the command 
  behave the same as the old LISTMENU argument).
  
   - @set
The @set directive 
  lets you set the value of arbitrary variables but until now these were only 
  valid within the command itself - there was no way for a variable set in one 
  command to be used in another command. In Opus 11 the @set 
  directive can now set variables that can be local to the current file 
  display, the current Lister, or global, and are persistent from one command to 
  another. They can also optionally be saved to disk so they will survive a 
  reboot (for example, Lister-local variables are stored in the default Lister 
  or Lister Layouts). The main use of this functionality is to allow buttons to 
  set variable values that can then be read by scripts.
To set 
  global variables prefix the name of the variable with glob:. 
  Prefix the name with src: and dst: to make 
  the variable local to the current source or destination tabs, and prefix the 
  name with lst: to make it local to the Lister. If you want 
  the variable to be saved (survive a reboot) add an exclamation mark - for 
  example, glob!:varname.
   - @ifset
The @ifset 
  directive can now test if a variable has previously been set by the 
  @set directive (although it can't actually test what the 
  value is - only if it exists or not). For example, 
  @ifset:$glob:foo would test if a global variable called 
  foo had been set.
A button on the file display toolbar 
  can also use @ifset:SIDE=left or 
  @ifset:SIDE=right to distinguish between the two sides in a 
  dual-display Lister.
  
   - @ifexists
The @ifexists 
  directive allows simple branching in a command based on whether 
  a drive or path exists.
  
   - @functype
The new @functype 
  directive is used to set the type of an embedded function. Previously 
  embedded functions were always assumed to be standard functions, but using 
  @functype you can use scripts or MS-DOS batch commands as 
  embedded functions as well. For example, the following command would open a 
  new Lister with an embedded script function that runs in the context of the 
  new Lister:
Go 
  NEW
[
@functype:script
@script:vbscript
' script function 
  here
]
Use @functype:script to specify a 
  script function and @functype:msdos for an MS-DOS batch 
  function.
  
   - @icon
The new @icon 
  directive lets you create buttons that dynamically change their icon based on 
  the test of a Set-command clause. The default View Mode 
  Cycle button uses this to change its icon to reflect the current 
  view mode.
Set 
  VIEW=Cycle
@icon:largeicons,VIEW=LargeIcons
@icon:smallicons,VIEW=SmallIcons
@icon:listmode,VIEW=List
@icon:powermode,VIEW=Power
@icon:thumbnails,VIEW=Thumbnails
@icon:tile,VIEW=Tiles
@icon:detailsmode,VIEW=Details
Each 
  @icon directive in the button specifies the icon to use, and 
  the Set directive to test for. For example, if 
  VIEW=LargeIcons tests as true, the icon called 
  largeicons will be displayed on the button. If none of the 
  @icon tests match then the icon set in the button itself will 
  be used as the default image.
In the special case of a three-button 
  button, @iconp: and @icon!: directives can 
  also be used in any of the child buttons to change the icon of the 
  parent. @iconp: used in one of the child buttons will 
  set the icon of the parent (but do nothing to the child 
  button). icon!: used in one of the child buttons will 
  set the icon of the parent as well as of that child button.
  
   - @toggle
The @toggle 
  directive can now control whether a button appears selected (checked) 
  or deselected (unchecked) based on the test of a Set-command clause. Normally 
  buttons that run the Set command appear checked or unchecked 
  based on the state of that Set command itself, but using 
  @toggle you can run one Set command and test 
  for another. You can also test for multiple Set clauses at 
  once. For example:
Set 
  VIEW=Details
Set 
  COLUMNSADD=thumbnail(0,96)
@toggle:if&COLUMNSTOGGLE=thumbnail
Normally 
  this button would appear checked whenever the view mode was set to 
  Details. However using @toggle we have added an 
  additional test - the Thumbnail column must also be present for 
  the button to be checked (the ampersand specifies that the test is in addition 
  to the one provided by the command - if you leave out the ampersand then only 
  the clauses in the @toggle directive will be 
  tested).
You can test for multiple Set clauses by 
  separating them with semi-colons. For example, you could leave out the 
  ampersand and still test both the view mode and the column using the following 
  directive:
@toggle:if 
  VIEW=Details;COLUMNSTOGGLE=thumbnail
You can also negate the 
  result of a test with the exclamation mark in front of the Set 
  clause. For example, to make the button appear checked in any mode 
  other than Details:
@toggle:if 
  !VIEW=Details
The 
  @toggle directive can also test for the existence of a 
  variable (similar to the @ifset directive). For this to work, 
  the directive must be the very first line of the button, and the variable you 
  are testing must have tab, Lister or global scope.
