Editor page: Help text that explains how things work

[neoneye]

Problem

Currently there is zero help. It's up to the user to explore the UI.

Solution

Make several videos. Each video explains how one tool works.

Explain the tools inside the Tools menu, such as: selection, copy, paste, fill, rotate, flip, crop.

Explain keyboard bindings.

S = Select
D = Draw
F = Fill
X = Flip X axis
Y = Flip Y axis
0-9 = Pick color 0-9
O = Jump between overview and edit.
Ctrl Z = Undo
Ctrl Shift Z = Redo
Arrow keys = Move pixels around inside selection
