enhancement: more keyboard shortcuts

[robertvazan]

Is your feature request related to a problem? Please describe.
It's a bit subjective, but current selection of shortcuts is a poor fit. There's a shortcut for settings, which are rarely accessed and not keyboard-friendly anyway. On the other hand, I often edit the last prompt instead of asking followup questions and there's no shortcut to start editing it and no shortcut to submit changes.

There are no shortcuts in the new Playground either, which makes it impossible to use the playground in the streamlined fashion described in #987. Notice the wide range of shortcuts in NovelAI (although NovelAI made the mistake of using Alt, which is impractical on keyboards that replace right Alt with AltGr).

Current WebUI shortcuts use three-key combinations, which are usually only used in text editors with several dozen shortcuts. Simpler two-key shortcuts should be used whenever possible.

Describe the solution you'd like
Maybe collect a list of the most common workflows and optimize shortcuts for them, preferring the more ergonomic shortcuts for the most frequent actions.

I can't find the keyboard shortcuts. But in the same vein, I would love a shortcut for "New chat".

@ddegner You are not alone: #1007. Look at the bottom right corner of the screen.

There's another keyboard shortcut that I absolutely love in OpenAI's Playground interface -- [Ctrl]+[Enter] to Submit, no matter where you are (e.g. editing previous replies). Having to move my hands away from the keyboard in order to manually click Submit slows me down.

Having escape close the current window (i.e. settings) and return also work on tags and other small input fields would be nice

Why do the shortcuts use so many modifiers? This is not ergonomic at all.

It's not like this is emacs, there are only a few shortcuts. All of them could be cmd+letter, e.g., cmd+k for new chat (which is what Claude uses).

The shortcuts could also be user-configurable, which would be much better.

ChatGPT Keyboard shortcuts.

[NightMachinery]

@tjbck Well, their choices are simply bad. I don't see why an opensource UI should imitate them without reason. Of course, there could be "hotkey packs" that configure the shortcuts to imitate ChatGPT for people used to that (IntelliJ does this to make it easy for people coming from other IDEs), but ChatGPT is a very new product, so I don't think this is worth it. Open WebUI should just go with ergonomic shortcuts.

Anyhow, I don't care about the defaults. If I can change these shortcuts, that's enough for me.
