Discussion Overview

The discussion revolves around the use of ALT-numberpad shortcuts for inserting special characters on Windows and Mac operating systems. Participants share various character codes and their experiences with these shortcuts, as well as historical context regarding their usage.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant shares specific ALT-numberpad codes for characters like µ, ±, and ° on Windows.
  • Another participant provides equivalent shortcuts for Mac, suggesting alternatives and encouraging a switch to Mac.
  • A later reply emphasizes the broader concept of using ASCII character shortcuts, referencing an ASCII table for additional characters.
  • Additional codes for accented letters and other symbols are mentioned, including codes for é, ², and ³.
  • A historical perspective is provided regarding the use of invisible characters in file names for security purposes in DOS.

Areas of Agreement / Disagreement

Participants express differing preferences for operating systems, with some advocating for Windows shortcuts while others promote Mac alternatives. The discussion includes both shared knowledge and competing views on the best methods for inserting special characters.

Contextual Notes

Some participants reference specific ASCII characters and their codes, but the discussion does not resolve which operating system shortcuts are superior or more widely applicable.

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.
