<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&mdash;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:

Finishing the edit is done by pressing <kbd>&crarr;</kbd> or <kbd>Tab</kbd>.
The <kbd>ESC</kbd> key allows to exit an edit without changing the clock. If an
entry is mis-typed so that the new value would be illegal (for example,
resulting in more than 30 frames when Timecode is set to 30 frames per second),
the clock will reset at the end of the edit, and move the cursor back to the
start to allow for another try.

<h2>Avoiding the mouse entirely</h2>
<p>
There is a shortcut available to edit the transport
clocks entirely without the mouse. It can be found in
<kbd class="menu">Window &gt; Keyboard Shortcuts &gt; Transport &gt; Focus On
Clock</kbd>. If bound to a key (<kbd>&divide;</kbd> on the numerical
keypad is the
default), then pressing that key is equivalent to clicking on the primary (left)
transport clock, and editing can begin immediately.
