[Feature request] Keyboard shortcuts for showing errors

[sauron918]

It'd be quite useful to be able to trigger error popup with some keyboard shortcut while typing without touching the mouse.

Use case: I'm typing some code. I see the code snippet highlighted in red, but I still should hover the mouse cursor to be able to read what's wrong with it.

@sauron918 yes, good suggestion. Thanks for raising. I will aim to include this in the next release.
