currently in v0.5.5 when you click the keyboard shortcut link in the help sidebar, the Keyboard shortcuts page opens as the main page.
i think it would be useful to be able to reference keyboard shortcuts in the sidebar while editing a page (i think it was like that in previous versions?) .
maybe it could be something as simple as allowing for shift-clicking of the current link to open in the sidebar? or perhaps a different keyboard shortcut could open a shorter, more concise keyboard cheatsheet in the sidebar?
