# Custom mapping for the Drop Alt Keyboard.

A really simple set of changes/fixes

# Features and changes:

## *ESC is now Grave Escape.*
Changes KC_ESC for grave escape - Escape key is also `/~ when used with the modifier key.

## *RGB timer switch off*

There is a timer that turns off RGB lighting after a set time. This is defined by 

    #define  IDLE_TIMER_DURATION  20000  //how many milliseconds before RGB turns off

## *Keyboard chatter fix*

I have left the debounce settings and instead changed

    wait_us(1); //Delay for output
to 40 instead of 1 which works for other keyboards as I was getting lots of keyboard chatter on all keys previously. 20 seemed to still let key chatter go through. Seems to be working well since.
