Create virtual space macro:
var scimoz=komodo.view.scimoz; scimoz.virtualSpaceOptions=scimoz.SCVS_RECTANGULARSELECTION|scimoz.SCVS_USERACCESSIBLE;
Set this property for virtual space macro: Properties / Triggers / Macro should trigger on a Komodo event / After file open.
Create caret left macro:
komodo.view.scimoz.charLeft();
Bind Left key to caret left macro: go to Properties / Key Binding / New Key Sequence and press Left.
Create caret right macro:
komodo.view.scimoz.charRight();
Bind Right key to caret right macro: go to Properties / Key Binding / New Key Sequence and press Right.
If you want to use Fix whitespace on save option (in Edit / Preferences / check Show Advanced / File Saving), you need to check Always clean current line, otherwise whitespace won't be cleaned when in virtual space and an error message will be displayed.
