[dmitry-saritasa]

Path: Projects/iwinkit/
 .docker/
 _commons/
 _externals/
 _hooks/
 _templates/
 _test/
 app/
 apps/
 assets/
 src/

in this screen if I click Ctrl-b nothing happens

if I quit with another Ctrl-f click and then click Ctrl-b I get this

[dmitry@DMITRY ~]$ Projects/iwinkit/" bash: bash_execute_unix_command: cannot find keymap for command [dmitry@DMITRY ~]$ Projects/iwinkit/"

my .bashrc

# .bashrc
[[ -s "$HOME/.qfc/bin/qfc.sh" ]] && source "$HOME/.qfc/bin/qfc.sh"
qfc_quick_command 'cd' '\C-b' 'cd $0'
qfc_quick_command 'joe' '\C-p' 'joe $0'

any ideas?
