methods presented (eg. shortcut, or editor loaded, or source loaded, etc).
Would be nice if we could set a tool to trigger on more than one, so maybe
replace the drop-down trigger list with a listicon with checkboxes or such?
(I realize some will be mutually exclusive, so not checkboxes for all).
Reason for asking: I want to trigger something on editor startup, and also
whenever a source code is loaded, and source code closed. To do this now
I need to set the tool three times in the tool editor.
