Would it be possible to add a deselect shortcut

[indignant]

Pixelorama version:
v0.8.2-stable

OS/device including version:
OSX Catalina 10.15.7

Issue description:
It's very difficult to deselect after using the rectangle selection tool. In Preferences -> Shortcuts there's not a shortcut listed for deselect. esc and delete don't do anything. Searching for a shortcut does not return results.

So I guess the issue is either:

1. There's not a quick way to deselect a selection
2. There's no documented way to deselect a selection

Steps to reproduce:

1. Use the rectangle selection tool to select something
2. Note that there's not an intuitive way to deselect

Thanks for making Pixelorama, it's a fun piece of software!

Hello,
The selection tool is being rewritten for the next update. This might be implemented in it.

Sorry, I forgot to close this issue. A deselect shortcut was implemented in #457 and this change will be included in the next version! There's still not a way to change the shortcut, but there will most likely be in a future update (see #309)
