=====Key Bindings and Keyboard Shortcuts=====
CATS allows users to use shortcut keys to navigate through the system. You can also modify which keys you press to take certain actions in CATS, such as changing the size of the font on a screen. Key bindings are per-user settings. 

====Customize Key Bindings====
Go to **User Preferences > User Settings**. 
[{{:cats:settings:menu_userpreferences_usersettings.png|cClick on User Preferences, then User Settings to open your settings.}}]

Click on the Appearance tab, then the Key Bindings button to open a list of bindings.
This shows the current keyboard shortcuts for accessing CATS functionality.
[{{:cats:settings:usersettings_keybindings.png|Click on the Appearance tab, then the Key Bindings button to open a list of bindings.}}]\\ 

Double-click on a line to set the keyboard shortcuts for that action.

<note tip>Bindings can be a one or two key combination. Use "Nothing" for the Modifier for a single-key combination (only permitted for F keys, aka Function keys, as otherwise you might call actions accidentally.</note>

First, choose the **Modifier**: Nothing, Control, Shift, or Alt. 
[{{:cats:settings:usersettings_keybindingsmodifierdropdown.png|Select the Modifier key from the drop-down box.}}]

Next, choose the **Function** key: Letter or Function keys F3 through F12.

For example, choosing Modifier ''Control'' and Function ''R'' for the Screen Font Reset option means that when you push Ctrl and R on the keyboard together, the Screen Font will reset its size.

Pick the **Save** button to continue, then choose a new key-binding, or choose Save on the next two screens to exit the settings area.

===Escape [Esc]===
The escape key lets you exit a menu or edit screen. It will cancel most activities. Changes made will not be saved. In scans, [Esc] will only cancel the changes to the current (highlighted) record.
For menu selections, [Esc] will return you to the previous menu without taking action.
===F1===
Use F1 to call up the CATS wiki.
===F2===
Use F2 to save data you have entered and to exit an edit screen. It can also be used on a screen to **continue and apply or cancel**.
