The basic formula is:
This action will audibly and visibly alert you when the timer has expired. The "when the timer ends" option lets you choose how many button presses are needed to turn off the alarm and start the next timer. You can pause the timer at any time with a short press to pause and later resume. Pressing and holding for 2 seconds skips the current phase and moves to the next one.
Note: This action times things differently than the standard method; the fourth break is one long break interval instead of a short break into a long break.
