Go further with this.  Don't map it to a single key, use it as a modifier so other keys have more functionality.  using CL+hjkl as arrow keys is great for VI users, CL+WASD for gamers - either way you don't need to move your fingers as much.

I use and recommend https://ultimatehackingkeyboard.com/, which defaults to putting the mod key in place of caps lock (it's fully programmable, so you can do what you like.  On Windows, https://www.autohotkey.com/ is extremely flexible.

When I was a student at Fullstack Academy, a coding bootcamp, they had us all do this (mapping it to the control key), along with a few other changes to such settings like making the key repeat rate faster. I think I got this script from them.

For Linux users on US Keyboards, you might want to try making Caps Lock the multi key (also called the compose key). On Cinnamon this can be done by going to Keyboard > Layouts > Options... > Position of Compose key, and other desktop environments probably have similar settings.

This lets me type umlauts (ä, ü, ö), foreign currencies (£, €, ¥,), copyright/trademark (©, ™), and a bunch of other stuff. For example, "ü" is made by typing Compose, u, and " in sequence. I also added the line

<Multi_key> <backslash> : "λ"

to my ~/.XCompose file so that I can type λ efficiently; this is useful when writing Lisp code.

Chromebooks replace the caps lock key with a search key - which is functionally equivalent to the windows keys on windows. E.g. search+right goes to the end of the line.

I use ProtoTyping: https://github.com/pnutus/ProtoTyping

How it works:

Capslock as modifier, hold it to use right hand for:

ijkl like wasd where:

i : to move cursor one row up

k : one row down

j : one character left

l : one character right

————————

u : one word left,

o : one word right,

h : to go to beginning on line,

key right of L : to go to end of line.

————————

Then also use modifier with left hand at the same time as Capslock to:

s : selecting text with movement commands described above. E.g. Capslock + s + o, to select the next word.

d : deleting text with movement commands described above

————————

Examples:

E.g. Caps + d + h to delete everything to the left of the cursor on the line. If you need to delete multiple lines just: (Caps + d + i)x3, e.g. to delete three rows. (very useful in programming)

E.g. (Caps + s + u)x3, to select the 3 words to the left of the cursor, so you can then copy them e.g.

This helps you not have to move your hand to the mouse or to the arrow keys as much. Your hands stays in the right position for touch typing (fast typing) where index fingers rest on f and j. Just release caps for a bit to write, and quickly move around holding down caps.

You can use it in any app, not just code editors.

The backspace key is also a pretty inconvenient reach. I have my capslock key remapped to backspace and it's wonderful.

Absolutely.

My caps lock has long been Control. I use ErgoEmacs for easy use of editing commands like delete/select word forward, delete/select word back, up line, up par, etc.

These are laid out systematically in ErgoEmacs, so are easy to learn and remember.

Only tangentially related:

for more fun and speed, learn to use the trackpad with your thumb(s) while your fingers stay in home position.

Use a wrist rest so your arms aren't tensed holding your hands in place.

All of these are independent. For the love of Pete remap your caps lock key to a modifier if you haven't. MacOS encourages this by putting it in system settings.

Personally, I've had my Caps Lock key bound to Escape for quite a while (I'd suggest a few years now?). It has been lovely and fits perfectly with my keyboard-driven workflow. Pairs great with Colemak-DH, which is my layout of choice.

I haven't found myself ever missing the Caps Lock key's original functionality, and my blank laptop keycaps mean I can have it bound without mental annoyance.

When was the last time you (intentionally) used your caps lock key?

yesterday

I may be the only one :)

I'd rather remap my right shift, which keyboard makers for some reason tend to make huge.

If you're on macOS and still want caps lock to be accessible for the rare occasions when you want it, you can use Karabiner-Elements to swap the caps lock key and the escape key.

When was the last time you (intentionally) used your caps lock key?"
today. and yesterday. and the day before that. I... can't say that about escape. i used that when i tried to close window in computer game that stuck? i can't think about other examples easily.


 

I went with https://hyperkey.app/

I use a Kinesis Advantage keyboard with the keys rebound to look like this (apologies for my poor graphic design skills):

https://i.imgur.com/Mv9FI7a.png

• Caps Lock is rebound to Backspace and Backspace is rebound to Shift.
• Right Shift is rebound to Ctrl + Alt + Super, which I use as a command prefix for window manager commands.
• "custom macro" uses the keyboard's built-in macro feature to send a sequence of four keypresses (Alt-G Ctrl-`), which I use as a prefix for some Emacs commands.
• By default, the keyboard has two backslash (\) keys. I use the OS keyboard software to rebind the second one to "–" (unshifted) and "—" (shifted), which for me are the most useful characters that aren't on a standard US keyboard.
