How to use the keyboard with one hand in Gnome 2.2
This page explains step-by-step how to set up Gnome for Linux so that you can use the keyboard with one hand by turning on 'Sticky Keys'. Some commands require a number of keys to be held down at the same time (for example, Ctrl + Alt + Delete). Sticky Keys enables you to select one key at a time.
Use the keyboard with one hand in Gnome 2.2
Step 1: Open the 'Keyboard Preferences' window
Click on 'System' in the menu bar, then 'Preferences' and then 'Assistive Technologies' to open the 'Assistive Technologies Preferences' window shown in Fig 1. Alternatively, press Alt + F1 and then use the arrow keys to move to 'System', then 'Preferences', then 'Assistive Technologies', and then press Enter.
Click the 'Keyboard Accessibility' button, or press Alt + K, to open the 'Keyboard Preferences' window.
The 'Accessibility' tab should be selected by default. If it is not, click on the 'Accessibility' tab, or press Tab until any of the tabs is highlighted, then press the left or right arrow keys until the 'Accessibility' tab is brought to the front, as shown in Fig 2.
Step 2: Turn on Sticky Keys
Below the 'Sticky Keys' header, tick the box next to 'Simulate simultaneous keypresses' by clicking on it or by pressing Alt + S.
You may want to change the settings so that Sticky Keys will turn itself off if two keys are pressed at the same time (for example, Ctrl + S to save). This is useful if you share your computer with another user. To activate this option, tick the box next to 'Disable sticky keys if two keys are pressed together', or press Alt + B to tick it.
Click 'Close' or press Alt + C to save your changes and return to the Gnome desktop.
Note: If this does not work it could be because your computer settings cannot be changed due to local IT policies - contact your local IT support for further help.
