I know what you mean. I recently started a job where they have quark, and am now saying why can't quark use the same keyboard shortcuts as InDesign.
After being to aggravated with Quark taking away features in 6 that use to be in 4 such as the Open Publisher (similar to edit original image in InDesign), I convinced them to buy InDesign. If I could only convert the 2 projects I inherited from Quaker to InDesign, but InDesign does not open Quark 6 and I have not utility to convert downwards in Quark. Well the printer will have to deal with making EPS files for each page so Goudy Bold does not bitmap on the PC.
