@acegikmo your “t”s are on the bottom and “b”s on the left 

s/b/l/g
s/t/b/g

@dpwiz yeah?
Show threadl'empathie mécaniqueAug 15, 2023

@acegikmo so the l’s would be on the left and b’s on the bottom.

also, s/a/x/, so x’s would be on a row/column intersections

@dpwiz what do you mean by s and x?
Show threadzl2todAug 15, 2023
@acegikmo @dpwiz
s/a/x/ is line editor notation for replace "a" with 'x".
The g on the end s/a/x/g makes it global, replacing a with x throughout the document.

I'm going to have to read up on my matrix notation too.
There's an s// example here. Sorry.
