# About the Timecode Calculator

You can use the numeric keypad to work with timecode. When you click a timecode field, the numeric keypad appears with the full timecode.

Use the numeric keypad to do the following:

- Go to the frame with a specific timecode.
- Calculate timecode from frame counts, and vice versa.
- Switch between drop and non-drop timecode (NTSC only).
- Convert drop timecode to non-drop timecode, and vice versa (NTSC only).

When you use the numeric keypad as a timecode calculator, some keys have a different function.
