In Vim, if you type
:help into the status bar, you get a window with this (contents truncated to the relevant bits):
*help.txt* For Vim version 7.4. Last change: 2012 Dec 06 VIM - main help file ... USER MANUAL: These files explain how to accomplish an editing task. Jump to a subject: Position the cursor on a tag (e.g. |bars|) and hit CTRL-]. |usr_toc.txt| Table Of Contents Getting Started ~ |usr_01.txt| About the manuals |usr_02.txt| The first steps in Vim |usr_03.txt| Moving around |usr_04.txt| Making small changes |usr_05.txt| Set your settings |usr_06.txt| Using syntax highlighting |usr_07.txt| Editing more than one file |usr_08.txt| Splitting windows |usr_09.txt| Using the GUI
Say I want to see more information about this item
|usr_07.txt|, what command do I type?
I tried this:
Jump to a subject: Position the cursor on a tag (e.g. |bars|) and hit CTRL-].
But my terminal window has mapped
ctrl - to "decrease text".
