function defined in hui-treemacs.el.
Signature
(smart-treemacs)
Documentation
Use a single key or mouse key to manipulate directory entries.
Invoked via a key press when in treemacs-mode. It assumes that its caller has already checked that the key was pressed in an appropriate buffer and has moved the cursor there.
If key is pressed:
(1) on or to the left of an entry icon, run the treemacs TAB command
to expand or collapse the entry;
(2) elsewhere within an entry line, display the item, which may be a
directory, for editing, normally in another window;
(3) at the end of an entry line: if an Action Key press, invoke
action-key-eol-function, typically to scroll up proportionally;
if an Asisst Key press, invoke assist-key-eol-function, typically
to scroll down proportionally;
(4) at the end of the first or last line of the buffer, quit this
Treemacs invocation.
