Map Key

How can i change the "PDF" map key to prompt me to pick a location to put it in. I'm guessing it's in the config.pro file but i don't know what to change it to if i'm correct.

mapkey pdf @MAPKEY_LABELPDF;~ Command `ProCmdModelSaveAs`;\

mapkey(continued) ~ Close `main_dlg_cur` `adbFile_cb`;~ Open `file_saveas` `type_option`;\

mapkey(continued) ~ Close `file_saveas` `type_option`;\

mapkey(continued) ~ Select `file_saveas` `type_option`1 `db_617`;\

mapkey(continued) ~ Activate `file_saveas` `mydocs_pb`;~ Activate `file_saveas` `OK`;\ <--here ??

mapkey(continued) ~ Select `intf_profile` `pdf_export.PDFMainTab`1 `pdf_export.PDFContent`;\

mapkey(continued) ~ Select `intf_profile` `pdf_export.pdf_font_stroke`1 `pdf_stroke_all`;\

mapkey(continued) ~ Activate `intf_profile` `OkPshBtn`;\

mapkey(continued) ~ Activate `main_dlg_cur` `main_dlg_cur`;

thanks,
