Why doesn’t ctrl-s work in ISPF edit? – ah it does now.

I had been editing a file, saving it, and finding the changes were not being picked up. Looking back, it was obvious; I was using CTRL-S the familiar Linux command, instead of F3 on ISPF.

I fixed this by configuring X3270 (on Linux).

My file /home/colin/.x3270pro now has

...
x3270.keymap: mine
! Definition of the 'mine' keymap
x3270.keymap.mine: #override \
    Alt<Key>4:          String("\\x00a2")\n\
    Ctrl<Key>backslash: String("\\x00a2")\n\
    <Key>Escape:    Clear()\n\
    <Key>End:        FieldEnd()\n\
    Ctrl<Key>Delete:   EraseEOF()\n\
    Ctrl<Key>Right:    NextWord()\n\
    Ctrl<Key>Left:    PreviousWord()\n\
    Ctrl<Key>Up:    Home()\n\
    <Key>Control_L: Reset()\n\
    <Key>Control_R: Reset()\n\
    <Key>Prior: PF(7)\n\
    <Key>Next: PF(8)\n\
    <Btn3Down>:   PA(1)\n\
    Ctrl<Key>1:   PA(1)\n\
    Ctrl<Key>s:   MoveCursor(3,15) String("save") Enter()\n\

When I started a new X3270 session, Ctrl -S went to the command line, typed save and pressed enter. Job Done ! The numbers are 0 based, so 3 means line 4 on the screen.

This makes life so much easier!
