you can select tasks by:
 - single-clicking using the mouse
 - using the arrow keys
 - or vim movement keys (j/k)

you can undo/redo using familiar keys:
 - `Ctrl-Z` or `u` undo the last action
 - `Ctrl-Shift-Z` or `U` redo

currently, the undo stack does not persist across page loads, and the undo stack is only displayed in the developer console.

you can change a task's summary/name by double-clicking on it or with vim editing commands:
 - `i`/`I` to enter edit mode with the cursor at the start
 - `A` to enter edit mode with the cursor at the end
 - `S` to enter edit mode with the full summary selected

all of these put you into \"insert mode\". to leave insert mode, either click away from the editing to de-focus the text field, or press `Escape` or `Ctrl-[`.

you can add new tasks with these key commands:
 - `o` adds a new task after the selected task, ignoring the task's children.
 - `O` adds a new task before the selected task.
 - `Enter` adds a new task after the selected task.
    if the selected task already has children, the new task will be the new first child.
 - `Alt-Enter` adds a new task as a child of the selected task.

note that `Enter` and `Alt-Enter` both work while you're editing a task summary! this means that you can easily add a bunch of tasks in one go - just keep pressing `Enter`!

if you press `Backspace` or leave insert mode while a new task has an empty summary, the new task will be deleted. you can also delete the selected task by pressing `Delete` or `Shift-Backspace`.

you can manage tasks with these keys:
 - `J` moves the selected task up
 - `K` moves the selected task down
 - `Tab` nests the selected task in as a child of its sibling (it \"indents\")
 - `Shift-Tab` un-nests the selected task (it \"un-indents\")
 - `-` hides a task's children
 - `=` shows a task's children
 - `.` marks a task done
 - `,` marks a task un-done

you can change a task's exposition/description by double-clicking on it or pressing `Shift+Enter` with this task selected. markdown is supported both in the summary and exposition!

you can change a task's points with `Shift-[1-9]` or set it to 0 points with `Shift-0`.

 - `1` displays the task list
