Alt-=: Math Word

The space-delimited word at the cursor will be evaluated as a math expression.

If you want to use spaces in your expression, wrap it in double quotes. They will be removed before the expression is evaluated.

•  Note:  = is the plus-and-equals key on the main keyboard. TCC version 24 and later will call it “Plus”, but it’s still the plus-and-equals key, not the plus-sign key on the numeric keypad. Take Command uses Alt-Num- and Alt-Num+ to change the font size.

Alt-= is the default hotkey for this action, but you can change it with EDITKEYS /K5:key.
