What are useful alt-key shortcuts for symbols for Electronics.SE?
Note that your answer only works on Windows. Also, if it doesn't work for some reason, there's no way to view the source. It's much better (IMO) to use the HTML entities (ISO-8859-1). They're the same on every platform and browser, they're easy to remember and to use, and they don't introduce any ambiguity with character encodings into whatever storage system StackExchange uses.
The characters you pointed out are:
- μ -
- τ -
- Ω -
- ° -
- β -
Note that capitalization is important.
There are many others. An important note is that the less than and greater than symbols won't work in code at times - they're HTML reserved entities. If you have problems, use:
- < -
- > -
By the way, feel free to accept your own answer if you feel/it gets voted a better answer.
I just search for "ohm symbol" or "micro symbol" and copy and paste from the google search results :D
In word processors, I use autocomplete to convert "kohm" to "kΩ", etc.
:*:kohm::kΩ :*:mohm::MΩ :c*:uF::µF :*:rthz::√Hz :?:sup2::² :?*:+-::±
So when I type
Mohm it is automatically replaced by "MΩ". I can easily type "nV/√Hz", "Δ = 100°C", "47 µF±10%", "50 km²", "τ = 2π", etc without pressing Alt or memorizing code point numbers. This works in almost any text field, not just a particular app. See my script here.
(And, in general, please use Unicode when writing special characters. Don't use different fonts. It's extremely annoying to go to a manufacturer's website and see resistors written as "10 kW", for instance, because they used the Windows Symbol font and it's not displaying correctly.)
