I know many people like to remap Caps Lock to function as Ctrl. However that setup does not quite work for me. There is only one Caps Lock key on the left side of the keyboard. I need Ctrl on both sides of the keyboard, so that I can use the left Ctrl key while typing Ctrl+P but the right one while typing Ctrl+A.

There are other options as well, like remapping the Enter key to act as Ctrl when chorded or using sticky modifiers. I think using an ergonomic keyboard with two large Ctrl keys on both sides of the keyboard is probably the best solution. I've discussed some of these alternatives in more detail <https://susam.github.io/devil/#why>.

By the way, there are some vendors that still make Unix layout keyboards with the Ctrl key positioned where Caps Lock key usually is: <https://deskthority.net/wiki/Category:Keyboards_with_Unix_la...>.

I just leave Ctrl where it is and press it with the knuckle of my little finger. I do it just like the guy in the pic on this page, pressing the control key with his little finger: http://xahlee.info/kbd/how_to_press_control_key.html - because that pic is of my hand. (Xah might not recommend doing this all the time, but I've been doing this for nearly 20 years now and I've had no problems.)

For the past 3 years I’ve done the following remap Caps -> lctrl/esc, enter -> rctrl/enter, tab -> lalt/tab, backslash -> ralt/ backslash. Also have the physical right alt mapped to multi key/dead greek.

It works really well, and makes emacs much more comfortable to type in.

Downside is this keeps me locked to X11 and fighting the occasional app that reads the key codes directly.

Instead of making it an additional Ctrl key, you can also make it a new separate modifier key with XKB[1]. I've found this very useful over the years for WM-related key bindings, leaving the other modifiers for applications.

Tangentially, I really loathe how Wayland has no alternative to this. I'm expected to configure keyboard layouts in every DE or WM I use, which is a much worse UX.

I was very disappointed that Apple gave up that fight.

They also at some point joined the PC world in moving the nubs on their keyboard from "d" and "k", where you were more likely to notice if your fingers are not in their proper place on the home row. Now if your right hand is offset slightly to the right, you won't feel anything, which is less immediately noticeable than if the nub were under the wrong finger.

I use a HHKB because of this. On the Acorn Archimedes I learnt to type on, it wasn't an extra Ctrl, it was the Ctrl.

Caps lock was rightfully relegated to bottom left.
