Problem

I'm more productive when I can use keyboard shortcuts.
E.g. press left/right to move to previous / next image. Press space to toggle some viz. Press j/k to move up/down some slider.

Solution

MVP: Provide a way to map 80% of the keys to custom actions. It could be an optional argument to streamlit.button, streamlit.slider (two keys for up/down one step), etc.

Possible additions: Allow to map most keys, inclluding remapping 'c' which currenty clears the streamlit cache.

Additional context

Comes form personal need. Also mentioned here: https://discuss.streamlit.io/t/idea-keyboard-bindings/1976 .
