Additional keyboard shortcuts for Blocks#351

Moving here from Github Issues, following Bastian’s request:

This started from a conversation on Discourse:

Bastian Allgeier: more power shortcuts are definitely planned! We’ve already implemented Alt+Shift+Up & Alt+Shift+Down to add keyboard support to sort blocks and I’m more than happy to add more of them.

The original Github ticket was created as a place to collect/discuss ideas for useful Blocks keyboard shortcuts. First thoughts and ideas are documented there: https://github.com/getkirby/kirby/issues/3010

I would also strongly vote for implementing the keybord shorcuts that everyone knows, like Ctrl+B for bold text, etc.; it does annoy me sometimes that these keyboard shortcuts are not available.

See https://kirby.nolt.io/423 for a related idea

Would love to see some common keyboard shortcuts created for blocks.

Yes! I wish there was some sort of non-core plug-in that allowed for better keyboard functionality throughout KirbyCMS in general.
