The attached file(
had to rename task to task.txt, else MR upload not allowing) gives tab completion of task subcommands, project names and tag names.. read the file for full info.. file was located at /etc/bash_completion.d/ on my linux box.. presumably got put there by the installation routine..
to enable this feature on the kindle, need to put a reference to this file in the .bashrc file.. where's the .bashrc in the kindle..?
