Raise character in verbatim mode

  \colorlet{whiteish}{white}

How do I raise the minus signs in both lines in the green box by a couple of ex or thereabout?

Answer 1

You can define a raised minus sign with

\DefineLCDchar{rm}{00000000001111100000000000000000000}

(which raises the minus by one pixel) and use it like this

\textLCD[0]{19}|{rm}8+6|

Or, if you want the minus sign to be always raised, you can just redefine it with

\DefineLCDchar{-}{00000000001111100000000000000000000}

and use it normally (\textLCD[0]{19}|-8+6|). In both cases the result is

Edit:

With \DefineLCDchar the pixels in the 5x7 matrix are set. A 0 is "pixel off" and a 1 is "pixel on". The pixels are given from left to right and top to bottom. The picture from the manual shows this:
