+## Tmux
+
+You can use **navi** as a [Tmux](https://github.com/tmux/tmux/wiki) widget to reach your Vim commands, often used SQL queries, etc. in any command-line app even in SSH sessions.
+
+Add these lines to your Tmux config file to access **navi** by pressing `prefix + C-g`.
+
+```sh
+bind-key -T prefix C-g split-window \
+  "$SHELL --login -i -c 'navi --print | head -c -1 | tmux load-buffer -b tmp - ; tmux paste-buffer -p -t {last} -b tmp -d'"
+```
+
+Example cheatsheet:
+
+```sh
+% vim 
+
+# Quit without save
+qa!
+
+# Delete a paragraph
+normal dap
+
+# Generate sequence of numbers
+put =range(<start>, <stop>)
+
+% postgresql
+
+# Describe table columns in `psql` or `pgcli`
+select 
+   table_name, 
+   column_name, 
+   data_type 
+from 
+   information_schema.columns
+where 
+   table_name = '<table>';
+```
