I use Vim to edit text files on Linux. Commonly I connect to remote Linux machines using PuTTY from Windows.  I use GNU Screen commonly as well.  When using Vim inside Screen I am unable to use the Page Up key because Screen interprets it as a command to start copy mode.  I would like to use Page Up for its regular up-paging functionality.  How can I configure Screen to do this?
How to allow Page Up in GNU Screen?
