I used that command but forgot how to turn it on:
In sublime console, which is invoked by ctrl+` I typed something like ...
turn_on_debug_mode
... and sublime console started to log every command I run. For example, if I press right mouse button on the view and click Copy file path
then in the sublime console I found logging of this action with the name of invoked command like copy_file_path
.
So that was an easy way to grab names of commands that I could use in self-written sublime plugins.
The problem is that I do not remember how to turn that debug mode on.
