Provide more actions for binding to keyboard shortcuts #72

Open marcora opened 3 years ago

marcora commented 3 years ago

It would be great to have more actions available for binding to keyboard shortcuts. Also, it would be nice to have a drop down to select among a few common keybinding schemes, e.g., Vim-like or Emacs/Bash-like.

For the latter, as an example, selecting the "Emacs/Bash-like" scheme from the dropdown would set the following actions to the following keyboard shortcuts:

CTRL+A / CTRL+E | Go to the start/end of the line CTRL+U / CTRL+K | Delete from cursor to the start/end of the line CTRL+W / ALT+D | Delete from cursor to start/end of word (whole word if at the boundary) CTRL+X | Cut whole line and add to clipboard CTRL+C | Copy whole line to clipboard CTRL-V | Paste (insert) whole line from clipboard CTRL-Y | Paste (replace) whole line from clipboard CTRL+F / CTRL+B | Move forward/backward one character META+F / META+B Move forward/backward one word (or go to start of word the cursor is currently on) CTRL+D / CTRL+H | Delete character after/before under cursor CTRL+N / CTRL+P | Move to next/previous line CTRL+L | Delete everything

WIth META being Apple key on MacOS or Meta key on Windows/Linux

Given the similarities between Mercury and Sonic Pi, perhaps offering a similar scheme would help transitioning users from one system to the other. Screen Shot 2021-01-31 at 13 13 28

Thanks for this, I have not looked at all the keybinding options from Sonic Pi yet, also not sure if I want to have the same keybindings, but did include the option to jump words in the latest commit 07cf633b98e00676ca85a9651d76f4dfe7530029 with alt-j and alt-l. But having the option to switch between different shortkey "presets" would be interesting to look at!

Deleting characters (as opposite to backspace with delete key) is now included in 09f080c54269df439596b4c3c4dff053ad1f61a1
