The IPA (SIL) Keyman keyboard is a mnemonic keyboard definition which enters Unicode values for IPA. This version of the keyboard supports a mnemonic layout. This allows a user to type with any kind of keyboard, rather than just a US keyboard.
The keyboard layout is described in terms of an IPA chart rather than a keyboard. This is because many base characters are typed as a sequence of a letter followed by one of <, > or = which are characters used to change a base character to another base character. Diacritics are typed as sequences of an appropriate key. Details of the keyboard layout may be found in the "welcome.htm" document in the section on Keyboard Layout.
The default for this keyboard is to type a letter followed by a "modifier". For example, this sequence "b>" would produce "ɓ". If you wish to use the opposite sequence (>b) that is possible. Use one or the other of these options. Do not turn Before on with Keyman configuration and off with the RALT hotkeys.
SIL International has produced several Unicode font sets that allow for the transcription of linguistic data using the International Phonetic Alphabet and this keyboard. These fonts are:
