One such example is our AltGr of course, which generates Mode_switch or Iso_Level3_Shift. Given that Shift selects within a group, it stands to reason that another key can select between groups. Or expressed in our new vocabulary: When the Shift modifier is engaged, the second ( A) rather than the first ( a) keysym from the active group is taken. It sets a Shift modifier, a special flag that says to interpret other keys in a new way. But that doesn't print a "shift character". Holding down the Shift key creates a Shift keysym, of course. This is called a chord - like on an organ, you press several keys at once. CapsLock or AltGr can similarly be pressed together with other "normal" keys. You use it to get an uppercase letter where normally, you'd get a lowercase one, for instance.
Shift of course is a key you can hold and then press another key. US keyboard and Ivrit, or, if you appreciate pain, US and French layouts), that also adds one group (e.g. If you have more than one national layout (e.g. That layer is in turn part of another group: AltGr with and without shift. If you use AltGr (right alt) to get funny extra characters like € and that's another layer. Keys may have several layers, like with and without shift.
Then you have maps saying what keycode generates what keysym - if the key that has printed A on its plastic keycap has keycode 666, the standard mapping might be for keycode 666 to be translated to keysym A.
They're pretty arbitrary in that they have no meaning and depend on your hardware. If you know your xmodmap, you can safely skip this bit.įirst, you have keycodes. So I needed to find a way to put the cursor keys on the main keyboard.īefore I get started, let me run the basic vocabulary by you, so we're on the same page. The rub is, you don't have cursor keys that way. It did wonders for me when I tried the " upright mouse", so I think the keyboard may be beneficial, too. When you type, your hand are not parallel to your desk, but orthogonal to it. It's like hacking a typewriter in two in the middle, and then putting both halves of the keyboard upright so they keyboards aren't horizontal, they're vertical. Anyway, the SafeType is also a split keyboard, but they mean it. That said, I was very happy with the ergonomic ("split keyboard") Logi - it was good to my wrists, it held up for ten years, and it certainly is one gorgeous keyboard -, and if the SafeType doesn't do the trick for me, I'll be looking to get a variant of the Logi that's not wireless.
I'm debating a new keyboard, as this one starts to act up - I'm sick of wireless, I'm sick of batteries, I'm sick of PS/2-to-USB adapters, and it seems the hardware starts failing me, too.
