#                   For usage with iTerm2:
#                   In iTerm's Preferences > Profiles > Default > Advanced > Semantic History,
#                   choose "Run command..." and enter "/your/path/to/iterm_open_with \5 \1 \2".
# Usage: iterm_open_with $(pwd) filename [linenumber]
# $(pwd) = current working directory (either use `pwd` or $PWD)
# filename = filename to open
# lineno = line number
pwd=$1
file=$2

This didn't work as expected for me; nvim was opening, but not in a visible tab/pane. I had to choose "Run coprocess..." and use the command echo /your/path/to/iterm_open_with \5 \1 \2

I would be curious to see how it works via "Run command...", was this a gui version of neovim perhaps?
