+# Gipsy-King's Cornelius layout
+
+Common typing only needs a base and a symbols layer. Layer changes are on the
+thumbs *including* shift and non-english variants.
+
+The importance of having shift on your thumbs is that you don't need to press
+some letters with pinky OR ring, depending on shift.
+
+## Base QWERTY layer
+
+* Tab, Backspace, Space, Ctrl/Alt/Mod are similar to a generic keyboard.
+* Esc is like when you remap CapsLock to Esc on a generic keyboard (vim).
+* Enter is on right thumb and raises Symbol layer on hold, because you rarely
+  hold.
+* Shifts are on both thumbs!
+* Leftmost thumb changes to Xmonad window management layer.
+* Rightmost thumb is Right-Alt which is for `us-intl-altgr` layout (althoug I
+  use kmonad to universally map international characters on all keyboards).
+* `-` and `=` are on the lower pinkies.
+* `F20` is mic-mute on my thinkpad laptop.
+
+## Symbol layer (Raise)
+
+* Top row is numbers, bottom row are their symbols. Most people do it the other
+  way 'round.
+* Middle row has curly brackets, and some navigation and arrows.
+* Square brackets are on the lower pinkies.
+* ```~\|`` are places aroung top/outer corners.
+
+## Xmonad layer (Window management)
+
+I use Xmonad to completely manage windows with just my keyboard. This layer
+accommodates most shortcuts.
+
+## Fn layer
+
+Lastly, some macros, mousekeys (not used, really), some media keys, and the
+function-keys (I use them maybe once in a decade).
