Some may recall my previous trys, and failures, to create macros using screen commands.
I was using exec tied to a bindkey in screenrc to run a shell script which contained a series of the stuff commmands to send instructions to the current application. It didn't work. By experiment I found that switching to another window and doing the shell script at the cli worked. So I used bindkey with a select # command to go to that window; followed by exec to run the shell command; the last command in the shell script was a select to return me to the application window. Joy, it works seamlessly as desired. Useing this approach any number of screen based macros can be developed. -- Thanks to all who offered advice. XR
