cmd-/ctrl-r lets one redefine the last search (at least in the german version of FileMaker) AND will run the current script when the focus is on the scriptworkspace in a script
If one does a search ie for altering data and checks some scripts at the same time (scriptworkspace..), cmd-r will run the script, in today's OS, it's hard to recognize the active window - it will happen
Please use different shortcuts for those actions - one can easily destroy data...
(btw. I _believe_ that there is allready a report around - but I gave up searching for that on the iPad)
