## Manage hot keys


**To manage hot keys:**


1. To display a list of all current hot keys, on the **Settings** menu, click **Show Hot Keys**, or press Shift+H.
2. In the **Hot Keys** dialog box, you can:
  - Save the hot keys that are currently listed (click the Save button at the bottom of the dialog box)
  - Load saved hot keys (click the Load button at the bottom of the dialog box)
  - Revert all the hot keys to their default settings (click the Default button > Macro (inline-media-image)

 at the bottom of the dialog box)
  - Specify custom hot keys (in the **Command** column, find the required command and double-click in the **Key Sequence** column). For details, see [Specify custom hot keys](#CustomHotKeys).

When you click Save, you can specify a file name and save the current hot keys as a *.*HotKeys* file to:


*C:\Users\Public\Documents\Vicon\Tracker4.x\username\HotKeys**\*


If you import a .*HotKeys* file from another user or machine, make sure it is in this folder path so that you can select it in the Hot Keys configuration menu.

Specify custom hot keys

In the Hot Keys dialog box, you can specify custom hot keys for both current hot keys (ie, overwriting the default hot keys) and for commands listed in the Hot Keys dialog box where the Key Sequence column is blank (ie, for which there aren't currently specified key sequences).


**To specify custom hot keys:**


1. Open the **Hot Keys** dialog box (select **Settings** > **Show Hot Keys** or press SHIFT+H).
2. In the **Command** column, find the required command and double-click in the **Key Sequence** column.
3. Depending on whether you clicked a blank cell:
  - If you clicked on a blank cell (ie, a key sequence is not currently specified), with the **Set Hot Key** dialog box still open, press the sequence of keys you want to specify.
  - If you clicked on a current key sequence, in the Set Hot Key dialog box click Clear and then press the sequence of keys that are to replace the original sequence.
  You are warned if your custom key sequence will replace an existing key sequence.
4. If you want to save your custom hot keys, remember to click Save at the bottom of the dialog box.
5. Click OK.
