Entering Arabic text
For those without an Arabic keyboard, there are two ways of entering Arabic text: virtual keyboards and keymaps.
The virtual keyboards are activated using the 'Show keyboard' button on the various search dialogs. Two layouts are provided - Windows Arabic 101 and 'Digital Orientalists'. Tools are provided to let you build your own layout.
The default virtual keyboard is set via the System Options dialog.
To use the virtual keyboard simply click on the required character. The 'Shift' key will stay active until another key is clicked; use this method to input the 'upper' row of characters.
Using keymaps allows your native keyboard to output Arabic characters using a 'map' - a key, or a sequence of keys, is converted into the mapped Arabic character. The default Arabic keymap is called 'Buckwalter' and corresponds (almost) to Tim Buckwalter's transliteration scheme (External reference). With this map active, typing 'kataba' would output كَتَبَ
Details of the default Buckwalter keymap are here
Keymaps are disabled by default and may be enabled via the shortcut Ctrl+K,E and disabled by Ctrl+K,D, or via the status line:
Once enabled they apply to all text entry items that require Arabic text i.e. the search dialogs where the target is Arabic text - root, headword and Arabic word search.
