i have a string that contains 3 characters that vary, it looks like this: board=XYZ

note: sometimes X=Y, or Y=Z (they can be either a letter or a number). thus, sometimes the string will read like this: board=K66.

what i want to do, is to find every instance where the variable pattern looks like "XYY" and switch the order to be "YYX". can emeditor do this using the regular expression function? or can it only be done via script/macro?
