 The default mapping for toggling indent guides is <Leader>ig. You can easily
 map it to other keys. For example:
 >
-  :nmap <Leader>ig :IndentGuidesToggle<CR>
+  :nmap <silent> <Leader>ig <Plug>IndentGuidesToggle
 <
 
 You can also map some other commands that are not mapped by default. For
 example:
 >
-  :nmap <Leader>ie :IndentGuidesEnable<CR>
-  :nmap <Leader>id :IndentGuidesDisable<CR>
+  :nmap <silent> <Leader>ie <Plug>IndentGuidesEnable
+  :nmap <silent> <Leader>id <Plug>IndentGuidesDisable
