The available diacritical characters follow those used by the Windows keyboard, detailed below, but by using the Option key and the parent Latin character (rather than using Ctrl+Alt).

To install this keyboard, download and unzip the file, and then double-click on the file called "KRCdiacritics".

At the on-screen prompt, choose to install the keyboard for the current user.

Now restart your Mac.

Once your Mac has restarted, open System Preferences and then Keyboard. In the Keyboard dialogue, choose the Tab labelled 'Input Sources' and click on the '+' icon towards the lower half of the dialogue window.

In the popup, choose 'English' in the language list on the left, and then 'KRC Diacritics' from the list of available keyboards, and then click 'Add'

Ensure that the checkbox to 'Show Input menu in menu bar' is checked, and you will see a flag icon in the bar at the top of the Mac's screen. Clicking on this will allow you to switch between your available keyboards.

Select 'KRC diacritics' from the list shown when you click on the flag, and all of the diacritic shortcuts should now be available.

You can make KRC diacritics your default English keyboard by removing the standard English keyboard from the list in the 'Input Sources' dialogue, should you wish.



The available diacritical characters follow those used by the Encyclopaedia of Islam for each of the languages, and most of the characters will be available by using Ctrl+Alt and then the parent Latin character. However, a couple of combinations have had to be moved due to limitations of available key combinations:

Glyph Character Unicode ID Shortcut
ء ʾ U+02be Ctrl+Alt+0
ا ā U+0101 Ctrl+Alt+a
ص U+1e63 Ctrl+Alt+s
ض U+1e0d Ctrl+Alt+d
ط U+1e6d Ctrl+Alt+t
ظ U+1e93 Ctrl+Alt+z
ع ʿ U+02bf Ctrl+Alt+9
و ū U+016b Ctrl+Alt+u
ى \ ي ī U+012b Ctrl+Alt+i
چ ç U+00e7 Ctrl+Alt+c
ش ş U+015f Ctrl+Alt+x
ك ğ U+011f Ctrl+Alt+g
ك ñ U+00f1 Ctrl+Alt+n
  ı U+0131 Ctrl+Alt+j
  ö U+00f6 Ctrl+Alt+o
  ü U+00fc Ctrl+Alt+y

In addition, capital versions of most characters can be obtained by pressing Shift alongside Ctrl+Alt.



Note that the keyboard will be installed for the language that your PC is using at the time of installation. As this custom keyboard is based on the UK QWERTY layout, it is advised that you ensure your PC is set to British English before starting your installation.

Once you have downloaded and extracted the file, and are ready to install the custom keyboard follow these instructions:

  1. Open File Explorer and navigate to the setup.exe for the keyboard layout.
  2. Run the file.
  3. Grant the app admin permission to install
  4. Open your PC's Settings app.
  5. Go to Time & Language.
  6. Select the Language tab.
  7. Select the current language.
  8. Click the keyboard button under it.
  9. The current and new keyboard layout will be listed. Remove the one you do not want to use.
  10. Restart your PC

The custom keyboard should now be available, either as your default keyboard, or via the language switcher if you have set your PC up to use more than one keyboard layout.
