solution for deleting multiple emails

[lostforawhile]

after searching and searching, and having to delete emails one after the other, I finally may have found a solution, if you select the particular email client you want to delete messages from, then press the button with the four squares {help on name} right next to the FN key, it gives you the coveted pop up menu to select all. YAY!! on this same subject, I keep running out of memory, is a there a catch somewhere where stuff is being stored?
