[Idea] Menu Navigation Hotkey's

Simple and straight forward.

Hotkeys to navigate menus and such quicker. 

[+] = Elements menu.

[tab] = jumps to the next tab in the main workspace. Can also jump to the next tab in the active element creator.

[-] = Closes the Elements menu

[backspace] = moves back a tab

And any others anyone else could think of. This would be useful for those who are far more familiar with the keyboard.
