Controls summary at the bottom of the editor window

[chexo3]

Having to remember everything as a new user is annoying, it'd be nice if there was a list of the node editor's controls. Could be as simple as just listing them, but could also be contextual (when hovering over nothing, show controls to create a node, when hovering over a node, show controls to manipulate and delete nodes)

Plus this allows for more complex contextual controls. For example, a shortcut to create labels or comments, for example C+L, and C+R (For Create Label and Create Remark respectively. Remark is basically an old school word for comments in a program.)

It'd also be nice to have more in-game documentation, with diagrams. For instance, so I could see what each thing in the editor does. Mouse over hints would also be useful: I could hover over a part of the editor I'm not familiar with to get more information. Like, hovering over the save icon would say "save gate"

This is also stuff that could be upstreamed to the ZCPU and E2 editors, or even to Starfall (not sure if they use wiremod editor)
