tmux-config .tmux.conf:41: syntax error and .tmux.conf:100: unknown key: if

Thanks for this awesome config file. I have two issues with my Mac (Majave 10.14.6 ) setup.

unbind }    # swap-pane -D
unbind {    # swap-pane -U

/Users/liuj1/.tmux.conf:41: syntax error

if I commented line 41, then I have

/Users/liuj1/.tmux.conf:42: syntax error

It has syntax error, but if I add \ like below, it has no error, had look with previous bugs seem it is mentioned something similar

unbind \}    # swap-pane -D
unbind \{    # swap-pane -U

This line not working

bind \ if '[ #{pane_index} -eq 1 ]' \
     'swap-pane -s "!"' \
     'select-pane -t:.1 ; swap-pane -d -t 1 -s "!"'

It complains:

/Users/liuj1/.tmux.conf:100: unknown key: if

I add \ like below, and it returns no error.

bind \\ if '[ #{pane_index} -eq 1 ]' \
     'swap-pane -s "!"' \
     'select-pane -t:.1 ; swap-pane -d -t 1 -s "!"'

After I got these 2 changed, the rest works fine.

It looks like with my Mac, need to escape { } and \

on Kubuntu 20.04, using konsole I had very similar problems. the above two suggestions fixed 2 of 3 issues. the 3rd was a custom vertical split (C-a \ ) I was using : C-a | , is std. I tried escaping it with another \ but that failed, so I just resorted to binding i . makes sense to me. thanks for previous efforts : made my life much easier.
