I find it easier to compose derivations in offline latex software, which is TexMaker, and then post it to PF if I need to seek help or discuss something. This works well except for in-line TeX: TexMaker uses a 'commence inline TeX' code that is the same as the 'end inline TeX' code, which is just the dollar sign. Double dollars, which on PF denote a non-inline passage of TeX, don't work on TeXmaker. PF uses the codes (open sq bracket)itex] and (open sq bracket)/itex] for inline code. These are 'asymmetric' between the begin and end code symbols whereas TexMaker has 'symmetric' symbols. TexMaker doesn't recognise the (open sq bracket)itex] approach and PF doesn't recognise the single-dollar approach. This makes it messy to copy between TexMaker to PF becauise all codes for inline TeX have to be altered one by one. There is no global-replace that can be done. Is there any code that PF's latex engine will recognise as both a 'start inline code' and 'end inline code' command? Alternatively, does anybody know of any other 'asymmetric' commands for inline code that I could try in TexMaker. I have tried itex & /itex, latex & /latex & tex & /tex. Thank you.
