Function Key Feature

The left toolbar also works as a Function Key and is similar to a control click (Windows) or an option click (Macintosh). When this feature is used, it acts as an indicator to the tools that they should behave in a different manner than they normally would. For example, the function key feature can be used to enable multiple selection within the Drawing Canvas or to constraint the proportions of a figure as it is resized with one of the handles.

To enable this functionality, hold and press on the lower half of the Drawing Toolbar where no tools are present. After approximately 1 second, the toolbar will turn red as an indication of the function key feature being enabled. It will remain enabled as long as the utilized finger/thumb remains held on the toolbar.

The standard dark gray toolbar will reappear as a visual indicator of the function key being disabled when the finger is released.

The Function Lock option may also be used to lock the Function Key Feature. It can be helpful for maintaining the aspect ratio of multiple figures during resizing without having to hold down the toolbar. It is also a useful option for enabling the one handed operation of TouchDraw. To enable this option, tap on the Settings Button in the Top Toolbar.

Tap on the Usability Submenu and then tap on the Function Lock On/Off Toggle Slider. It will appear with a green background when enabled.
