I think many TC users are very lucky and so happy because shortcuts or hot keys exist in TC and are customizable. Keyboard is more productive because it stay in the same place and mouse must be located first, after that must be driven carefully to the fix point. I prefer a reduced action, how much is possible, to change focus from mouse to keyboard or inverse.
I saw in forum search how F2 became a complementary rename filename inline, how it was add other shortcuts and so on. History...
Now, it's a good opportunity to add inside TC 7(beta), some other usual shortcuts and remove the obsolete, in order to became a non-beta version. I mean, spring time clean up!

Bellow you will see what already exist default in TC and a list of proposal new hot keys, able to be inserted into TC:

Also, I'm surprised about SHIFT+F4 witch is unknown or undocumented function, but everybody still use it. Many shortcuts are not mine, are folkloric in TC community, but must be a little standard in every languages and with any wincmd.ini, by force of habit.
The last part is from wincmd.ini file, shortcuts section. It can be replaced very easy, in copy-paste-land.
