Dual function keys for home row; with support for fast (touch) typing.

Home Row Fu

Make the home row keys (A S D F and J K L ;) act as modifiers (Shift, Ctrl, Meta, Alt) in addition to their default function.

Installation

This is a Interception Tools plugin so you need to have them installed. The plugin itself has no external dependencies and can be compiled as simple as:

make
make install
# Invoke the following command only if you install for the first time, as it
# will overwrite any existing config file!
make install-config-file

Caveats

The following caveats only pertain to the keys the plugin is configured to handle; all events pertaining to the other keys are just passed through.

• Visual lag when entering one of the handled keys. This is by design: the keys are being sent either after the next key press (during burst typing) or after the key release.

• Need to slow down for using modifiers in order to wait out the burst typing time window (200 msec by default).

• Key Repeat events are discarded, because on longish press (more that 700 msec by default) keys are being "locked" to be a modifier and would insert nothing when released.

TODO

• Fix interaction of e.g. the real Left Shift holding and pressing A (which emulates) Left Shift.
