keyboard shortcut on tool hover

A handy feature would be, when you hover your cursor over any tool icon on toolbar; that in addition to the tool name pop up, that that same pop up also displays the current keyboard shortcut for that tool.

Because, If we forget the keyboard shortcut, the pop up would be a handy reminder for future uses; especially for the same painting session.

There is no other easy place to find the keyboard shortcut...not in menus, keyboard prefs setting panel too much work, saved shortcuts list .xml to much trouble to find/open.

Would be an easy code is already handy, pop up windows already available....just add some text to pop up from a table.
