That Symbolics keyboard looks like a minor variation on the PC keyboard in some regards.<p>The Control key is in the same wrong general location; it wants to be where Symbolics has Rubout, and where PC keyboards have Caps Lock.<p>Another bad design was the DEC VT100 terminal keyboard. It put Ctrl to the left of a Caps Lock key: [Ctrl][Caps Lock][A][S][D][F]. Yikes!<p>Apple II had this right:<p><pre><code> [Ctrl][A][S][D][F]
</code></pre>
Commodore 64: Ctrl weirdly high:<p><pre><code> [Ctrl][Q][W][E]
[Rs][Sl][A][S][D]
</code></pre>
Ctrl next to Q. Rs = "RunStop", Sl = "Shift Lock".<p>In any case, I need the LeftControl to be <i>somewhere</i> far to the left, just like LeftShift.<p>Here is why: I <i>only</i> use those! I never use RightShift or RightCtrl.<p>When I type Ctrl-Q, Ctrl-W, ... Ctrl-Y, Ctrl-A ... Ctrl-G, Ctrl-Z ... Ctrl-B, I'm always using the left pinky, plus another finger of the same hand.<p>Same with the capitals of those letters: LeftShift with left pinky, plus left hand finger.<p>Whenever I have to use Alt, which is rare, I use LeftAlt, and it's quite awkward with the left side keys due to its position.<p>Here is why I use only LeftShift: from time to time ALL CAPS material occurs, like when typing identifiers such as PTHREAD_MUTEX_INITIALIZER. The only way to type these fast without using the Caps Lock key is to hold down shift with one finger and just type with the remaining nine fingers. Changing between left and right Shift in order to always use the opposite Shift key would be slow and prone to typing mistakes. Once you can type arbitrary material blindingly fast with your pinky holding down the LeftShift key, it makes no sense to think about the existence of RightShift.
