Question about the use of symbols

[bmulcahy]

I understand it greatly improves the readability of the code but how the hell do I type some of these symbols without copy and pasting? especially ʹ

On Linux, it is Ctrl + Shift + U + (hexadecimal)unicode.

On Windows, it is apparently Alt + (numeric keypad)'+' + (hexadecimal)unicode – though it seems that the registry key HKEY_CURRENT_USER/Control Panel/Input Method/EnableHexNumpad (type REG_SZ) must be set to 1 if it is not already.

Characters used frequently in the code:

• φ: U+03C6 (greek small letter phi)
• λ: U+03BB (greek small letter lambda)
• Δ: U+0394 (greek capital letter delta)
• θ: U+03B8 (greek small letter theta)
• δ: U+03B4 (greek small letter delta)
• ʹ : U+02B9 (modifier letter prime)

• Unicode Block 'Spacing Modifier Letters'

I do tend to use ctrl-c / ctrl-v quite a bit!
