+Notes on bash tricks that could help you become more productive by leveraging
+keyboard instead of using the mouse.
+
+## Creating new terminal tabs
+
+In order to create a new bash terminal tab using the keyboard one can use the
+following keys:
+
+-   *Ctrl + Shift + t*
+-   *C-S-t* using Emacs terminology
+
+## Switching between tabs
+
+And to switch between different terminal tabs one can use:
+
+-   *Alt + tab_number* (example: *Alt + 1*)
+-   *M-{number}* using Emacs terminology
+
+## Searching at the history
+
+Other than this, you can search through the terminal history using *C-r* which
+will use the **reverse-i-search** utility.
+
+## Kill a tab
+
+Finally, to kill the terminal you are currently in, the **exit** command must be
+enough.
