How to use a keyboard shortcut
Press Tools ▸ Customize… ▸ Keyboard to change keyboard shortcuts in LibreOffice.
Traditionally, keyboard shortcuts are written like so: Alt + F1. This means that you should press the Alt and F1 keys simultaneously. This is normally best achieved by holding down the modifier key (such as Ctrl or Alt or the Super(windows logo) key) and then pressing the second key once. You can then release the modifier key.
Finding keyboard shortcuts
Finding system keyboard shortcuts
To find (and change) system-level keyboard shortcuts, one can (at least in later, GNOME-based distros, e.g. ubuntu karmic) run the Keyboard Shortcuts applet, e.g. via System>Preferences>Keyboard Shortcuts on the main menu.
Finding application-specific keyboard shortcuts
While there are many standard keyboard shortcuts (see below), most applications also have keyboard shortcuts which are specific to themselves. These can normally be found in the pull-down menus at the top of the application's screen. The example below shows a menu in OpenOffice.org Writer, with the keyboard shortcuts highlighted:
