The Klipfolio "CTRL-E" shortcut in formula editor to "Select Function" is redundant as most common platforms provide some shortcut to select all text (CTRL-A on Windows, CMD-A on OS X).
Furthermore, it overrides and blocks the standard OS X keyboard shortcut (CTRL-E) to move the cursor to the end of the line.
Is there even a reason to promote "select all" with a special shortcut key? (I.e. is this such a common action when editing a formula that it needs to be mentioned at all, let alone have a special custom shortcut key assigned to it?)
This feature request is to remove the CTRL-E shortcut and allow it to be used by the system for what it is otherwise globally used for (move to end of line). Users can still use platform standard (CTRL-A or CMD-A) means to select all text if desired.
