Add more ways to move out of mathfield

Prerequisites

• New issue

Description

It is possible to leave the math field using

• Right and left arrow keys
• Tab

However, a few other editors that I’m used to also make it possible to “submit” an expression. This means, when the user hits Enter and isn’t in command mode, the mathfield loses focus. Furthermore, it would be great if the up and down arrow keys could also be used to leave a math field. This is quite useful when you have multiple math fields in a row. An example of the behavior I’m looking for.

Actual behavior

The mathfield keeps focus

Expected Behavior

It should be possible to leave the mathfield using those keys as well

• Enter
• Up or down

Notes

I sadly don’t think that this can simply be implemented in userland by using the shortcuts feature nor with onKeystroke.

Lastly, I’m more than willing to open a PR that implements this. However, I’d need a bit of guidance regarding where to start.

The codepen is here: https://codepen.io/arnog/pen/OJNWLNJ

To check if the mathfield is in command mode, check mathfield.mode === 'command'

@wlewis-formative yes, that’s correct
