Toolbar tooltip to also have key indicator

[mrvux]

Hello, this is a small one but really handy when starting with the editor, for the moment, for example, hovering toolbar on rotation shows :

It would be nice to have text as : Use Rotation Gizmo [E]

This directly shows which key is to be used to activate the relevant mode. This makes the whole editor much more self explanatory and user friendly.

Thanks
