F2 and F3 capitalize letters rather than stepping

[juacala]

When in debug mode, if I hit F2 or F3, it changes two letters my cursor is over to uppercase, and does not step. (F5 F6 F9 all work as one would want).

Is it possible there are other settings someplace that are conflicting with these key bindings?

[juacala]

It appears this is due to being run within a screen session. If use the debugger outside of a screen session, it works fine. Still, any settings I can use to fix this, and allow me to use it within a screen session?

If it is messed up inside screen but not outside you should check your terminfo settings.

• which escape sequence does the terminal/screen send for F5: try CTRL+V and then F5 in the shell
• what escape sequence is configured in vim for F5? :set t_f5?
• what mappings are there for F5: :map <F5>
