+# ollyhayes's keymap for [Corne Keyboard (crkbd)](https://github.com/foostan/crkbd)
+
+## Keymap
+
+After many years of changing my keymap often and reperatedly, I finally came to a stable version. I've been using this for a while now with only small tweaks every so often.
+
+All layers are activated only whilst the layer key is held, except the default layers.
+
+Lots of keys are repeated on both sides. I find this really useful for two reasons:
+
+* I like to have the option to use the opposite hand to hold modifiers shift/ctrl etc as the hand pressing the key, I find this really comfortable.
+* When using the mouse, I like to be able to do common things with just my left hand.
+
+### Colemak
+
+The base layer:
+

+
+### Navigation
+
+All things for moving the cursor around, inspired by vim.
+
+* `c←` is ctrl+left
+* `↓↓↓↓` is ↓ pressed four times
+
+![navigation](https://i.imgur.com/xfkA0ze.png)
+
+### Symbols
+
+The shifted number row and all brackets and other symbols.
+
+* `a/t` is alt-tab for window switching in windows/linux. Using some special code to release alt when the punc key is released, this works quite nicely.
+
+![symbols](https://i.imgur.com/t9Jygs1.png)
+
+### Specials
+
+Some extra symbols (linux only for now) that work by sending UTF sequences. Layer activated by holding both punctuation layer keys.
+
+![specials](https://i.imgur.com/AtPWKrA.png)
+
+### Numbers
+
+Numbpads (left version is reversed so 1, 2, 3 are easy to reach with one hand (like on a regular keyboard).
+
+Also the keys to switch the default layer are here.
+

+
+### Functions
+
+Function keys, nothing too interesting.
+
+![functions](https://i.imgur.com/ttrw3FJ.png)
+
+### Games (default layer)
+
+Used for some games, qwerty with space bar and alt for the left hand.
+

+
+### Qwerty (default layer)
+
+Mostly for guests.
