Your use case

This should have a keyboard shortcut as it's faster than using the mouse

Hey, I would like to implement this, seems really handy! 👍

I would use CTRL + ALT + K. That shouldn't cause any conflicts from my testings and feel familiar as is it still quite similiar to CTRL + K.

I think usability also could be improved if we automagically select and format the word the caret is currently at. E.g. Matrix would become [Matrix]() if the caret is at the last character of Matrix. What do you think?

Would you mind if I add a shortcut for formatting code as well? With a non-qwerty based keyboard layout the back ticks are quite awkward to type, so this would improve usability by a lot imo. Github e.g. also has Ctrl + E for this. We could use the same shortcut.

Should I create a new issue for the code shortcut?

[SimonBrandner]

Great! Please go ahead! I don't think you necessarily need to make an issue for the code shortcut

@alexanderstephan how about macOS? What would be the equivalent shortcut there, especially to avoid conflicts?

@UwUnyaa Currently, the aim is to use Ctrl/Cmd + Shift + L, more info at the end of the linked PR above. This should not cause any problems from my testings. The review from a UX designer is still pending, so this is still very much up for discussion.

From my understanding, these changes should be made in matrix-org/matrix-react-sdk, right? I can only find relevant code there, and I see the potential of this being the first issue I work on.
