I was working with someone who had 4 or more ISPF logical screens, within his ISPF session, and was typing SWAP 1, SWAP 2 etc until he found the one he wanted.
I told him about the SCRNAME command. In the editor screen type SCRNAME EDIT, swap to the SDSF and type SCRNAME SDSF, swap to the one displaying OMVS files and type SCRNAME O etc
To get from one screen to another type SWAP EDIT or SWAP O and it jumps to the window you have defined.
How do you know what sessions you have defined ? Easy use the SWAPBAR command to display the list on the bottom line
