Thanks for the explanation. So the space after \textdir TLT is meaningful but the one after \lefttoright isn't. (I guess, I should have used \textdir TLT\relax. I'm going to use the high-level \lefttoright command from now on.)
in addition to wolfgangs explanation: you can use grouping foo {\righttoleft oof} foo it's best to keep the spaces at the outer level so no foo{ \righttoleft oof }foo ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
