+# swedish-lindhe ErgoDox (EZ) keymap
+
+This is a setup that is very useful for me. It may or may not be for
+you. I will use it in conjunction with the A5 overlayed sv_SE layout.
+
+The layout is subject to change (in particular I'm thinking about adding
+a macro recording feature), but it have not changed much the past year
+or two so you can expect it to be stable enough to learn it.
+
+A5: http://aoeu.info/s/dvorak/svorak
+My xkb map: https://github.com/lindhe/dotfiles/blob/master/usr/share/X11/xkb/symbols/se-A5
+
+The most major points:
+======================
+
+I think the layout image can be found on
+[www.keyboard-layout-editor.com](http://www.keyboard-layout-editor.com/#/gists/d84bc5915707cb30a4f9f754e06ecea3)

+
+* Easily accessible F11 key for fullscreening
+* Print screen
+* Middle mouse button for X-paste
+* Improved reachability of meta buttons (LCtrl, LALt, AltGr, LGui etc.)
+* Cluster Page Up/Down + Home/End by the right thumb
+* Vim-like arrow layout in right bottom row
+
+* Set media layer toggle to right thumb (Enter)
+* Set apostrophe on LCtl (putting it next to some other small
+  characters)
+
+L1:

+
+* Full function key layout
+* Teensy button
+
+L2:

+* Improved layout of emulated mouse buttons
+
+LED behaviour to binary+CAPS
+============================
+
+The ErgoDox LEDs on this layout is using the two rightmost LEDs as the
+two LSB in a two digit binary number, representing layer 0, 1, 2 and 3.
+The leftmost byte/LED indicates CAPS status.
