[Feature Request] key bindings, showing them

[o-jasper]

Currently no keybinding for rotating it? (v and h flip it though) Could also show what keybinding it is in the "onhover" text, and just state the keybindings in menus?

Could have : show a menu of all the possible actions that selects through as you type, selecting one and hitting enter runs it. But maybe that's a bit much.
