Rethinking the Keyboard widget

[Saq Imtiaz]

This is potentially more suited to the dev forum but I am posting here as it may be of interest to others.

I would like to discuss enhancing the core keyboard widget ( https://tiddlywiki.com/#KeyboardWidget ), at first as a plugin and later potentially for the core. Currently the widget only supports adding one keyboard shortcut at a time. So if you need to capture a few keys you end up with a crazy number of widgets quite quickly (example below)  with each one adding a DOM element.

<$keyboard key="ctrl+enter" actions=<<save-edit-bullet-actions>> >

<$keyboard key="tab" actions=<<indent-bullet-actions>> >

<$keyboard key="shift+tab" actions=<<unindent-bullet-actions>> >

<$keyboard key="ctrl+down" actions=<<focus-lower-bullet-actions>> >

<$keyboard key="ctrl+up" actions=<<focus-higher-bullet-actions>> >

<$keyboard key="alt+down" actions=<<demote-bullet-actions>> >

<$keyboard key="alt+up" actions=<<promote-bullet-actions>> >

<$keyboard key="enter" actions=<<save-bullet-actions>> >

<$keyboard key="alt+enter" actions=<<save-longform-actions>> >

<$keyboard key="escape" actions=<<cancel-edit-bullet-actions>> >

<$keyboard key="delete" actions=<<delete-bullet-actions>> >

<$keyboard key="alt+r" actions=<<rename-bullet-actions>> >

<$edit-text tag="textarea" autoHeight="yes" minHeight="1em" focus="yes"/>

</$keyboard>

I have considered having a list widget that loops through some tagged tiddlers to setup multiple keyboard widgets, and while a step in the right direction,  that too feels inefficient. One keyboard widget should be able to handle multiple assignments. 

The question is, what is an end-user friendly way to declare multiple key-action mappings when calling the widget?

One option is to pass it a filter that identifies tiddlers with key-action mappings, similar to what $:/tags/KeyboardShortcut does for the core.

( https://tiddlywiki.com/#Keyboard%20Shortcut%20Tiddler )

<$keyboard $filter="[tag[my-keyboard-mapping-tag]]"/>

Thoughts?
