Classic Edition Keyboard
The standard Classic Edition keyboard tables are files supplied in the aplkeys sub-directory named cc.din where cc is the standard 2-character country code, e.g. uk.din.
Note that the standard tables do not support the entry of APL underscored characters ⍙ⒶⒷⒸⒹⒺⒻⒼⒽⒾⒿⓀⓁⓂⓃⓄⓅⓆⓇⓈⓉⓊⓋⓌⓍⓎⓏ.
The standard table supports two modes of use; traditional (mode 0) and unified (mode 1). The keyboard starts in mode 1 and may be switched between modes by clicking the Uni/Apl field in the status bar or by keying * on the Numeric-Keypad.
The Classic Edition keyboard layout is close to that of the Unicode Edition, but does not include certain symbols which are only provided in the Unicode Edition.
