Tips

To add a task, write in the command line + new task and press Enter.
To delete a task, select it, write in the command line = and press Enter.
Press "Save changes" to actually store the modified task list to the wiki.
To display all tasks, write in the command line ? and press Enter.
To display all tasks without a context, write in the command line ? -@ and press Enter. This actually lists tasks without the "@" character.

Advanced users: you can use a command line "% tnwmr" to (un)check the status checkboxes (t=top, n=next, etc., you can have one or more like % Td). If the letters are lower case, the checkbox will be cleared, if uppercase, it will be checked.
