am using iTerm with Tmux, but I see this without tmux. If I hit
SHIFT+SPACE I get the escape sequence
^[[32;2u. Is there a way to suppress it or disable that escape sequence? I am not seeing it in my preferences as a predefined escape sequence
The solution depends on the application that enables the xterm
modifyOtherKeys feature. iTerm2 recently adapted/imitated/whatever this from xterm.
The xterm manual in turn mentions a page in the FAQ XTerm – “Other” Modified Keys which gives information on the feature, and in that page's Other Programs section points to an iTerm2 discussion where Nachman added the CSI u feature in January 2019. That gives the same information as
modifyOtherKeys, using a slightly different format (see
formatOtherKeys, which dates from 2008).
Here's a screenshot showing the preference:
The "?" help points to iTerm2's website, which is a bit lacking in depth (ymmv). My intention when I developed the feature was that applications would enable it temporarily, rather than making the terminal turn it on indefinitely.
