A keyboard mouse.
Cross Aiming Tool if you need it to be an acronym :-)
The goal is to minimize the use of a mouse, not to eradicate mice.
Intended usecase is to be able to keep the hands on the keyboard while writing.
Therefore dragging and scrolling is not supported.
Use "asdw" or arrow-keys to choose direction.
When the rhombe is small enough (8 key presses)
or when "e" is pressed, the mousepointer is placed
where the lines cross in the center of the rhombe
and the mouse is clicked.
To right-click press "r" instead of "e".
Press "q" to reset rhombes.
To start using a hot key on
Ubuntu 18.04: Download the cat_ubuntu standalone file and place it in a folder somewhere.
Open a terminal, go to the folder and change the program to executable with the command chmod 555 cat.
Go to Settings, Devices, Keyboard and scroll to the bottom to of
the list of shortcuts. Press + and add a shortcut. I use shift + ctrl + u.
The Command should be the path to cat_ubuntu (Eg /home/user/Desktop/cat_ubuntu)
Windows 10: Download the cat_win10 folder and place it somewhere.
Go into the folder in the file explorer and make a shortcut by right-clicking on the program cat
Move the shortcut to the Desktop, right-click the shortcut and add a keyboard shortcut. I use shift + ctrl + u.
