+# QFEnter
+
+QFEnter allows you to open a Quickfix item in a window you choose.
+You can choose the window by giving it a focus just before jumping to Quickfix window.
+You can also open multiple items at once by including them in the visual block.
+
+A normal mode example:
+![qfenter](https://f.cloud.github.com/assets/5915359/1632228/bb76dc72-5774-11e3-83d1-2933b95d5b81.gif)
+
+A visual mode example:
+![qfentervisualopt](https://f.cloud.github.com/assets/5915359/2006385/61c6f720-8717-11e3-806b-d0f276af3ef9.gif)
+
+## Usage
+
+In Quickfix window,
+
+**\<Enter\>**, **\<2-LeftMouse\>**  
+*Normal mode* : Open an item under cursor in a previously focused window.  
+*Visual mode* : Open items in visual block in a previously focused window. As a result, the last item appears in the window. 
+
+**\<Leader\>\<Enter\>**  
+*Normal mode* : Open an item under cursor in a new vertical split from a previously focused window.  
+*Visual mode* : Open items in visual block in a sequence of new vertical splits from a previously focused window.
+
+**\<Leader\>\<Space\>**  
+*Normal mode* : Open an item under cursor in a new horizontal split from a previously focused window.  
+*Visual mode* : Open items in visual block in a sequence of new horizontal splits from a previously focused window.
+
+**\<Leader\>\<Tab\>**  
+*Normal mode* : Open an item under cursor in a new tab.  
+*Visual mode* : Open items in visual block in a sequence of new tabs.  
+Quickfix window is automatically opened in the new tab to help you open other Quickfix items.
+
+You can change the key mappings in your .vimrc. The default setting is, 
+```
+let g:qfenter_open_map = ['<CR>', '<2-LeftMouse>']
+let g:qfenter_vopen_map = ['<Leader><CR>']
+let g:qfenter_hopen_map = ['<Leader><Space>']
+let g:qfenter_topen_map = ['<Leader><Tab>']
+```
+
+## Motivation
+
+Default opening methods for QuickFix items are quite inconvenient,
+
+- You cannot select a window in which a file is opened when you press `<Enter>` in Quickfix.  
+
+  > Hitting the \<Enter\> key or double-clicking the mouse on a line has the same effect. The
+file containing the error is opened **in the window above the quickfix window**.  
+*`:help quickfix`* 
+
+  It is inconsistent with other Quickfix commands like `:cnext` and `:cprev` which open a file in a previously focused window.
+
+- You also cannot specify the window when you use `Ctrl-W <Enter>`, 
+because Vim always create a new horizontal split window above Quickfix window and open a file in it.
+There is even no command for 'open in new vertical split window'.
+
+They are confusing and bother me every time, so I wrote a simple plugin to make up for these weak points.
+It's name comes from the most basic way to open a file from Quickfix window - the `<Enter>` key.
