How do you make the symbol that looks like an uppercase i or lowercase L and is commonly used in linking things on wikis?
The vertical bar, known also as pipe can be inserted at most text areas by:
* Pressing Shift + Backslash. (Not at all keyboards.) * Pressing Alt+124.
Whether a symbol is lowercase or uppercase is important. A lowercase m stands for milli- one one thousandth, an uppercase M stands for mega- one million. The m for metre should be lowercase, only units that are named after people have uppercase symbols, hertz Hz, watt W, henry H. So 10 megametres is ten million metres or one hundred million centimetres. 10 millimetres is one centimetre.
