update fzf default command to ignore .git folder:

export FZF_DEFAULT_COMMAND='
 (git ls-tree -r — name-only HEAD ||
 find . -path “*/\.*” -prune -o -type f -print -o -type l -print |
 sed s/^..//) 2> /dev/null'


installed vim-tmux-navigator, which allows you navigate in and out between vim and tmux panes using same shortcut keys

once installed the plugin, it default maps ctrl j/k/l/h for moving around vim windows

then add these lines to ~/.tmux.conf to enable the same keybindings for tmux:

is_vim="ps -o state= -o comm= -t '#{pane_tty}' \
    | grep -iqE '^[^TXZ ]+ +(\\S+\\/)?g?(view|n?vim?x?)(diff)?$'"
bind-key -n C-h if-shell "$is_vim" "send-keys C-h"  "select-pane -L"
bind-key -n C-j if-shell "$is_vim" "send-keys C-j"  "select-pane -D"
bind-key -n C-k if-shell "$is_vim" "send-keys C-k"  "select-pane -U"
bind-key -n C-l if-shell "$is_vim" "send-keys C-l"  "select-pane -R"
bind-key -n C-\ if-shell "$is_vim" "send-keys C-\\" "select-pane -l"
bind-key -T copy-mode-vi C-h select-pane -L
bind-key -T copy-mode-vi C-j select-pane -D
bind-key -T copy-mode-vi C-k select-pane -U
bind-key -T copy-mode-vi C-l select-pane -R
bind-key -T copy-mode-vi C-\ select-pane -l

since I use ctrl-l (clear screen) and ctrl-k (kill line) a lot, it bothers me a bit, so I need to re-mapped them:

bind l send-keys 'C-l'
bind k send-keys 'C-k'
