I'm looking for a tool that will tell me what my keyboard is sending to the operating system when i push different keys.
This is to help me answer this question How to get Cmd-left/right working with iTerm2 and Vim (without requiring .vimrc changes)? which has me trying to figure out why Vim treats my iTerm2 mapping of Cmd-left to Escape-[H differently from Home.
I tried unix's read, and it says that Home and Cmd-left both produce "^[[H".  I'm hoping that read is misleading me, and that some other tool will show how Home and Cmd-left are different (note: when I say, Cmd-left in this paragraph, it is when iTerm2's mapping is turned on).
Thanks!
