Has it worked for you? Do you see it as U+03BC or something?

I'll stick with 'us'. You could use 'mms'. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

But "us" works in most cases.

Depending on what the code is doing it can be a lot longer. That is the real concern in an ISR. -- Rick

And I have the character available in my editors (text and graphics) under dps but not via a single key; I have used it earlier but I think lately I just use "u". I suppose I can get used to "us" instead of "uS", but may be an option would be se-6 or sE-6... I still can't quite swallow the thought that S is invalid for seconds. I looked at my very old tek 465B, well, its front panel is also designated with lower case around the timebase knob. Dimiter

As long as readers have a reasonably modern newsreader, there should be no problem with the letter "mu" for micro - it is a standard character in the standard fonts on most systems. If someone has customised their desktop or newsreader to use a weird font with a more limited character range, then it might show up oddly. If there are any fans of command-line newsreaders, they should also see it if they have a utf-8 locale on their systems. As for typing it, that depends on your system and your keyboard. Windows is (as always) more limited. It should be easy for most non-English keyboard layouts, which separate the "Alt" and the "Alt Gr" keys - on my Norwegian keyboard layout, it's just AltGr-m. But if that doesn't work, character map is probably the least inconvenient method unless you can remember the Alt + numeric keyboard sequence. For Linux, you have other options. Again, depending on the keyboard layout, AltGr-m is likely to work - certainly on my Norwegian layout I can get a wide range of characters with combinations of AltGr, shift, and different keys. Then there is also the "compose" key - typically, this is not assigned by default, but you can set it up if you want it (I use the "scroll lock" key as compose). Then µ is compose + m + u.

Then µ is compose + m + u.Along with the often used ° - Alt-0176 ± - Alt-0177 mu is µ - Alt-0181 The zero is very important. Without it you get other chars. -- Rick
