    I thought you might find these useful. (I am amazed how many of my colleagues still type these longhand or have to find the symbol in a menu somewhere).

    On a Windows PC, with NUM LOCK on, hold the left hand ALT button and type the number on the number pad.

    ALT-230 = µ
    ALT-241 = ±
    ALT-248 = °

    Hopefully more suggestions will follow...

    hmm :rolleyes:

    on a mac (from the very first mac), alt-m = µ, shift-§ = ±, alt-shift-8 = ° etc :smile:

    get a mac ! o:)

    Excellent riposte.

    Being an open minded and tolerant community of intelligent professionals, we will not take this as an excuse to indulge in narrow minded Windows vs Mac vs Linux bashing.

    Nope, we will rise above that and celebrate the contributions of shortcuts for any colour of operating system.

    ...Especially the minorities...

    What you've discovered is the shortcut for inserting any ASCII character. You can use this for any of the ASCII characters on this chart, note that the second chart has the shortcuts you listed:

    There are four digit codes too. ALT-0233 = é. There is a big contiguous block of accented letters and other variations in that general area.

    Some others I know
    0176 - °
    0177 - ±
    0178 - ²
    0179 - ³

    Back in the DOS days, when I didn't want customers (or potential competitors) tinkering with my code, I would name the file with an ending ALT255. The "character" is invisible, but DOS would require it in the file name if you wanted to open, copy, or modify the file. Back before I had access to a decent compiler for dBase applications, I had to leave source code on customer computers, and a little extra security was necessary.
