4. Click the Tangent Curve command.
5. Click in the Press new shortcut key text box and press the keys on the keyboard to be used for a shortcut.

For example, for Ctrl + T, do not type Ctrl. Press the Ctrl key and the T key at the same time. If those keys are assigned to another command, the command name appears below.

6. In the Save in combo box, click the dropdown arrow and select the template in which the shortcut will be saved.
7. Click Assign if the keys aren't currently assigned to another command. The new shortcut appears in the Current Key/s list.

If the shortcut key you typed for the selected command is currently assigned to a different command and you press the Assign button, the original command/key assignment is overridden. When using that shortcut key, the command is executed instead of the command to which this shortcut was previously assigned.

All the shortcut keys that are saved in the document overrides the shortcut keys in the base templates and the Normal template.
The list of commands can be filtered by entering a search string in the 'Show commands containing:' edit box. The search is case insensitive and only commands with matching caption are listed. The category lists changes based on the matching commands.

Note:
The Macros, Menus, New Menu, and UIControls categories are always listed. To cancel filtering, leave the box empty and delete any blank space.
