+# Timed function layer keymap
+
+Amber's personal keymap for the Wraith, but with a custom timed function layer keycode.  `config.h` contains defines that you can edit to control various aspects of this function.
+
+## How does it work?
+We are reading QMK's software timer in `matrix_scan_user()`.
+
+Once the `TIME_TOGGLE` key is pressed, `layer_time_remaining` is set equal to `LAYER_TIMEOUT`, the layer defined in `LAYER_SWITCH` becomes active, and the LED on the Escape key (pin B0) will light up.
+
+Each time the matrix is scanned, the software timer is read, and the value of `layer_time_remaining` is decreased by `prev_loop_time` - the amount of time elapsed since the last matrix scan.
+
+When there are `TIMEOUT_WARNING`ms left in `LAYER_TIMEOUT`, the LED will begin to flash at intervals of `FLASH_PERIOD`ms.
+
+When there are `TIMEOUT_WARNING/TIMEOUT_SCALE`ms left, the LED will begin to flash at intervals of `FLASH_PERIOD/SPEED_SCALE`ms.
+
+When `layer_time_remaining` is equal to or less than 0, the layer defined in `LAYER_SWITCH` is removed from the layer stack.
+
+
+## What are the defaults?
+`LAYER_TIMEOUT` controls how long the layer will stay active for. The default is 10 seconds.
+
+`TIMEOUT_WARNING` controls how long the warning (LED flash) will occur before the layer becomes inactive. The default is 3 seconds.
+
+`FLASH_PERIOD` controls how long each LED flash interval is in the warning time. The default flash period is 250ms.
+
+`SPEED_SCALE` controls how many times faster the LED will flash in the second flash period. The default scale is 2, twice as fast.
+
+`TIMEOUT_SCALE` controls the length of the second flash period, relative to `TIMEOUT_WARNING`. The default scale is 4; for 750ms of the secondary flash period.
+
+`LAYER_SWITCH` is the layer that will be activated by the key. The default is layer 1.
