Went down a rabbit hole looking at keyboards on #AliExpress → number pads → mini-keyboards for shortcut keys and jog-dials (e.g. scrolling, zooming, volume). Some of these have up to 15 keys…

And then I thought of #JapaneseKeyboard options, and if anyone made a physical kana #FlickInput thumb keyboard like on smart phones (e.g #godan / #mozc)?

Or perhaps if these can be configured for up to 5 multiple presses, could map first key to あいうえお etc like older phones and then pass to IME for kanji?
