I wasn't sure from you previous post why you wanted to type this character. Is it something you often use, or was it just a random example of an Compose definition involving codepoints rather than more familiar letters and symbols? I would assume that someone who was going to use a Compose sequence to type the I-beam would already have their keyboard set up to make APL symbols available with a shift level. AIUI they would likely use the layout similar to the IBM 2741. On that keyboard, you could therefore type Compose and shifted B and N; see: https://en.wikipedia.org/wiki/File:APL-keybd2.svg For typing raw codepoints, your method will work in graphical applications like FireFox and, presumably, Desktop environments generally. In emacs, where I compose my emails, the sequence is a little different: Esc x i n s Tab c Tab Return 2 3 3 6 Return which stands for Meta-X insert-char (using Tab completion) followed by the codepoint. Or one can type: Ctrl-X 8 Return 2 3 3 6 Return or even: Ctrl-X 8 Return A P L Tab I - Tab which uses Tab completion to type APL FUNCTIONAL SYMBOL I-BEAM, the Sunday name of the symbol. People who use vi may have different keystorkes. Horses for courses. Cheers, David.
