jimeh's xkeysnail setup

The goal here is to use xkeysnail to make Linux keyboard shortcuts mostly behave the same as on macOS.

Pre-requisites

To be able to run xkeysnail as a non-root user / with sudo, we need to perform some initial setup.

Create a uinput group and add your user to it:

sudo groupadd -f uinput
sudo gpasswd -a $USER uinput

Create udev rules for xkeysnail:

cat <<EOF | sudo tee /etc/udev/rules.d/70-xkeysnail.rules
KERNEL=="uinput", GROUP="uinput", MODE="0660", OPTIONS+="static_node=uinput"
KERNEL=="event[0-9]*", GROUP="uinput", MODE="0660"
EOF

Reboot.

(Borrowed from here.)

Setup systemd user service

Copy service into place:

mkdir -p $HOME/.config/systemd/user
cp ./systemd.service $HOME/.config/systemd/user/xkeysnail.service

Reload user units:
```
systemctl --user daemon-reload
```

Enable service:

systemctl --user enable xkeysnail.service

Start service:

systemctl --user start xkeysnail.service

Check status of service:

systemctl --user status xkeysnail.service
