Photoshop shortcuts in GIMP
If you want to have Photoshop keyboard shortcuts in GIMP you should manage with ps-menurc file in the following directory: : he_way_to the_GIMP_foldertc\gimp.0
In order to set Photoshop v.6 keyboard shortcuts in GIMP you simply rename the file ps-menurc into menurc and move it to the folder: :\Documents and Settings\username\.gimp-2.6\
The shortcuts file from Photoshop v. 6 is distributed along with the GIMP shortcuts standard configuration file. But it was last updated in July 2005 that hints at fairly old combinations.
