Add CTRL+E shortcut to editor to bring sticker menu up

[nushea]

Description

Adds Ctrl+E as a shortcut to bring up sticker board. As there is the autocomplete there is no new shortcut to bring emoji board up, but it can be switched to kb only by pressing shirt+tab then space then typing out the query.

Note that this addition is to editor so the editor must be focused in order to bring the sticker menu up.

Fixes #949
