[Inkscape-user] Shortcuts not working

Good night :) I find that some keyboard shortcuts don't work, for example the # (Grid) and | (Guides) ones. May be it is because I'm using a Spanish- ISO keyboard on an English system? * I'm using Inkscape v0.48.2 on an iMac iSight —last and most powerful PowerPC iMac— running Mac OS X 10.5.8 (Leopard). Thanks :) -- Eneko Gotzon Ares I'm a beginner and my first impression about Inkscape is very good. Thank you very much to its developers :)
