The main window has the following components: menubar, toolbar, task/time window and status bar.

The Task/Time window
The various tasks are displayed in this window, along with the time accumulated for each in the current session and in total. Tasks being timed have a small clock icon next to the session time.
Subtasks can be created for each task. Double-clicking on a task displays or collapses its associated subtasks. The total time accrued for a task includes the times for its subtasks, as well as its own accumulated time.

The menubar

The File Menu
S File Save 	 Saves the current tasks and subtasks with their accumulated times
P File Print 	 Prints the window
R File Reset Session Time 	 Resets the total elapsed time for the current session to zero
Q File Quit 	 Closes

The Clock Menu
S Clock Start 	 Starts timing the selected task
Clock Stop 	Stops timing the selected task

The Task menu
N Task New 	Add a new task
N Task New Subtask 	 Add a new subtask to the selected task
Del Task Delete 	 Delete the selected task or subtask
E Task Edit 	 Change the name or accumulated time for the current task
There are two options for changing the time: Edit Absolute, in which the session and total names can be changed separately, and Edit Relative, in which a certain change is added to or subtracted from both the session and total times.

The Settings menu
Settings Configure Key Bindings... 	Opens a dialog to allow the user to customize the keyboard shortcuts
Settings Configure KArm 	Opens a dialog to allow the user to configure
The dialog has two tabbed panes: Saving, which configures the location of the save file, whether autosaving is enabled and the autosave interval, and Idle Detection which, when set, pops up an alert when no activity has been detected for a specified amount of time.
