Increase amount of text copied in iterm2 When I select text in iTerm2, the text it copies cuts off at after a certain (seemingly arbitrary) point.  I did a few tests and its usually between 800 and 1500 bytes of input.

Why is this, and how can I change the settings in iTerm2 to allow me to copy all the text I highlight?

Note: I don't have this problem in the default "terminal" application, just in iterm.
It should copy all text you have selected.  You should check under Preferences>Profiles in the Terminal tab how big your scrollback buffer is.  However it is specified in lines not bytes.
