When a user selects 'insert' mode on a screen, it reverts back to 'overwrite' mode on the next screen. Is there a setting to keep the mode insert/overwrite based on what the user has set? Or is this a default that's either one or the other and can only be changed per-screen?
Answer:
Yes, it is the default based on your settings in: Custom Settings > General tab > Keyboard emulation.
Differences between 3270 and Windows emulation:
Pressing left arrow to enter a text box from the right side:
3270 - cursor moves to end of data in text box.
Windows - all data in the text box gets highlighted
Pressing right arrow to enter a text box from the left side:
3270 - cursor moves to front of data in text box.

Pressing backspace:
3270 - cursor moves left one character at a time.
Windows - cursor moves left one character at a time as it deletes those characters
