#From his README:

• copy to clipboard

• Default font is system "mono" at 14pt

• Toggle light/dark mode now Alt-Tab instead of the frequently conflicting F6
• Alt-k and Alt-j scroll back/foward in history one line at a time
• Alt-u and Alt-d scroll back/foward in history a page at a time

(Additions before me.)

• Return to default font size -- Shift+Alt+Home
• Paste -- Shift+Insert

make
sudo make install

If you want transparency, run the following. (You will also need to have a composite manager, such as compton or xcompmgr running for the transparency to appear.)

make clean
patch < patches/transparency.diff
make
sudo make install

And to remove transparency, just unapply the diff patch and reinstall.

make clean
patch -R < patches/transparency.diff
make
sudo make install

You can change the transparency value by changing the alpha variable in the config.h file.
