+ CSCOPE settings for vim using popup and preview window
+""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+![image-20210314031215254](https://raw.githubusercontent.com/nmaiti/fzf_cscope.vim/master/screenshoot.png)
+
+
+
+
+
+ This file contains settings for vim's cscope interface to fzf (can use vim* >8 advanced popup feature), " plus some keyboard mappings that I've found useful.
+
+### Prerequisites  : 
+
+1. cscope  -- install using 'sudo apt install cscope' on ubuntu
+2. https://github.com/junegunn/fzf
+3. https://github.com/junegunn/fzf.vim
+
+### Installation:
+
+Install fzf & fzf.vim before installing fzf_csope.vim and using it
+
+`Using`  [pathogen.vim](https://github.com/tpope/vim-pathogen), and then simply copy and paste:
+
+```sh
+mkdir -p ~/.vim/bundle
+cd ~/.vim/bundle
+git clone https://github.com/nmaiti/fzf_cscope.vim.git
+```
+
+using [vim Plug](https://github.com/junegunn/vim-plug) add following in your ~/.vimrc
+
+```sh
+Plug 'nmaiti/fzf_cscope.vim'
+```
+
+### **key mappings**
+
+Search options - 
+```sh
+'s'   symbol: find all references to the token under cursor.
+'g'   global: find global definition(s) of the token under cursor
+'c'   calls:  find all calls to the function name under cursor.
+'t'   text:   find all instances of the text under cursor.
+'e'   egrep:  egrep search for the word under cursor.
+'f'   file:   open the filename under cursor.
+'i'   includes: find files that include the filename under cursor.
+'d'   called: find functions that function under cursor calls.
+'a'   Assigned: Assigned to this symbol.
+```
+
+```shell
+<Leader>k<search option key>  ------- search word/file under the current cursor
+e.g.sc
+<Leader>kc  -   find callers of current keyword/symbol
+```
+
+// Interactive cscope search
+
+```sh
+<Leader><Leader>k<search option key>  ------- search something
+e.g.
+<Leader><Leader>ks  -   find symbol
+```
+
+**NOTE**:
+
+1. These key maps use multiple keystrokes (2 or 3 keys).  If you find that vim
+   " keeps timing you out before you can complete them, try changing your timeout
+   " settings, as explained below
+2. cscope_map.vim can also be used independently with it's own key mappings. If not csope_maps.vim is not present fzf_cscope.vim can use csope_maps.vim's keyboard shortcuts for convenience of programmers.
+      In that case instead of '<Leader>k', '<Ctrl - \>' can be used.
+ 
+ **Self promotion**:
+ 
+ Try [zsh_vim config](https://github.com/nmaiti/zsh-vim-config/tree/to_plug) to_plug branch for latest vim features and plugins
