<h2>Changing clock values with the keyboard</h2>

<p>
|

New values for the clock can be typed in after clicking on the relevant clock.
|
||||
Clicking on the clock will show a thin vertical cursor bar just to the right
|
||||
of the next character to be overwritten. Time should be typed in the same
|
||||
order as the current clock mode—if the clock is in Timecode mode, it
|
||||
should be hours, minutes, seconds, frames. So, to change to a time of
|
||||
12:15:20:15 one would type
|
||||
<kbd>1</kbd><kbd>2</kbd><kbd>1</kbd><kbd>5</kbd><kbd>2</kbd><kbd>0</kbd><kbd>1</kbd><kbd>5</kbd>.
|

Each number typed will appear in a different color, from right to left,

overwriting the existing value. Mid-edit, after typing <kbd>3</kbd><kbd>2</kbd><kbd>2</kbd><kbd>2</kbd> the clock might look like this:
