When editing a button one can use JScript built-in editor to type code. Editor has syntax colouring. This colouring doesn't parse properly escaped quotes making user believe he/she has made a mistake in quoting which is not the case. Editor should properly "understand" that sequence of characters: /" is not finishing the String and such quote character is a part of it.
In example below, my button to search for selected movies in IMDB has incorrectly coloured code where in line 10 name looks like part of a string which in fact is a variable name.
