That is an argument for having altGR and the like, which is not a very integral way of inputting language.
With limited resources in terms of buttons available, what one has to work with is a case of less means more complexity in terms of input methods on the same keys.
Stateless or not, something must be done. Just as modifiers arent integral on a basic level, inversly L 1 2 and R 1 2 are very integral keys to the device.
I think media buttons and the mentioned space return , and . is more in tune seeing as this makes the typing experience into a 6 finger event rather than just the two.
It fortifies the handheld position, as it makes input on 10 finger impossible.
Which function to bind to which L or R isnt given, and you end up having to equally learn the hard way something that isn't intuitive. I can see the symbol, but i don't know where to get to it. Is worse than i see the letters, space must be somewhere.
6 fingers to type is more fluid than 2 and sometimes (rarely) having to go +4.
Another thing to have on L/R would be media buttons, play/pause, prev next and stop. In a closed position altGR is useless, but thats when i see the device as a primarily media-centric device, for which media buttons are usefull. Sound for the most part, but maybe also a presentation device.
Learning media buttons in a handheld state and having it available when the lid is closed is a great transfer function.
I dont really like modifier keys, especially custom ones. Instead a non-stateless mode-switch key is more natural to me. It would change everything but the keyboard to get the best of both from a media/game mode to input/browsing. The input switcher is in that area, so it makes sense for it to change only the gamepad and L R.
With two states the L and R could be their function ingame for how they are known to work, and mediabuttons also, which you dont really "need"
If it isnt 3 states with space and such too in one mode, the media-keys could be stateless modifier based buttons, at which point the non-stateless modifier argument crumbles.
Except, modifying with combos on mediakeys is not a common practice, and im having a little trouble picking that idea up mentally. On that token, id rather have scrolling and alt+tab's on dpad non-stateless, and then we are back to modes.
Its interesting to explore these options, and while im leaning towards all in on this drastic variation atm, i think there is much to yet find out and try.
What esentially im trying to do
http://www.keyboard-layout-editor.com/#/layouts/3b971382c90ab86b2aa83168386fa6b0 is -3 amount of keys away from trying to swing something on A-Z alone. Its a slippery slope from there.
http://en.wikipedia.org/wiki/Keyboard_layout#National_variants Germany, the whole of scandinavia, spain, france etc etc. They all use those keys, and the list is much longer.
It doesnt matter so much whats on the keys so much as they are there as buttons. If the button pressings are neutral they could be bonus keys for anyone else, something to use as press to speak in mumble or a screensaver button/ whatever you wish.
Also, whatever approach to having a set number of other keys, comes up 1 key short for me, or messes with conventions too much. Even when you do away with useless things such as caps lock.
In the original the white and black looked very stylish, which I feel the latter version is more quilty of implementing. Im glad that idea came into frutition on wb's effort, because it really cleans up the place.
Following that logic is not polluting other areas with chars. That is also a "free" idea that doesn't become systemic.
http://www.keyboard-layout-editor.com/#/layouts/863c0f526d79e1eac6eb786a44aaf7bf I also dont understand why ^ and so on is replacing &, thus shifting the /()= along where it doesnt belong. That is not US or US intl layout http://en.wikipedia.org/wiki/British_and_American_keyboards#PC_keyboards so it becomes not fish nor fowl, because altGR is a intl addition.
That was wrong, I am sorry, brain malfunction. 8 is ( and 9 is ) only on norwegian and german keyboards,
( edit: for reference its !"#¤%&/()=?` was thinking of this in remapping the ones that fall in between, in regards also to putting the F-row on numbers so you end up having to juggle a little anyhow, best to cast the odd balls in the air)
possibly others, but i agree that the standard is therein the US and UK one
