Thumb Keyboard Layouts

why not put shift to thumb

DionBridger says:

Xah Fly Keys Layout for Kinesis/Ergodox Keyboard what is the case for not putting shift keys on the thumb cluster?

thumb keys all used up. but alt layout can be designed... shift key is nasty. i tried to eliminate it or move to thumb, several effort over the years, but end up they stay where they are.

my thinking is that thumb keys are best for modifiers and pinkey keys the worst

yes. but i just haven't came up with a layout that put shift as thumb. one of the issue with modifiers in thumb is that, ideally, u want 2 for each hand. ideally, one should be enough. however, from experience, two is really much more ergonomic. because using the same hand to hold a thumb modifier and pressing another key, is just not comfy. so, that means, for each modifier, they need 2 keyspots in thumb position. this really strain the thumb spots. There's not enough thumb keys. There's control alt win/cmd and shift. because for thumb, for each hand, say right hand, really there are just 2 spots for comfy reach. beyond 2, there'd be some thumb movement. And if that key u need to press very often, as in every 1 min, such as shift. Then, u got a potential rsi inducing problem. thumb keys is relative new, but there's already lots report of rsi with thumb. e.g. thumb trackball, and from ergodox users. so, thumb keys, isn't some sorta cure all. we still need to be careful.

habit is the killer of progress

from 1990 to 2005, my fav keyboard is the generic cheap $5 keyboards.

Any other shape or new button position different than that i refuse to use.

This shows, that i was also susceptible by habit. When you have no problem, you no want “solution”. Till you type a lot and got Repetitive Strain Injury, then, you begin to appreciate those “odd looking” ergo design you used to laugh at.

People Do Not Like Trackpad?

xah input device research new finding: it seems, nobody like trackpad. Or rather, people prefer mouse or trackball over trackpad. Because, by searching amazon, there are not many trackpad makers, and not many sells. In context, there are tons of mouses, trackballs, pen tablets.

Microsoft Windows keyboard shortcuts: Alt + Space c vs Alt + F4

Windows little known tip: Alt+Space c is more effective than Alt+F4 . It'll work when sometimes the latter won't.

However, Alt+Space c shortcut is language dependent. If the operating system is set to French, it'll have different key.
