+Opening help in the current window				*help-curwin*
+
+By default, help is displayed in a split window.  If you prefer it opens in
+the current window, try this custom `:HelpCurwin` command:
+>
+	command -bar -nargs=? -complete=help HelpCurwin execute s:HelpCurwin(<q-args>)
+	let s:did_open_help = v:false

+	    execute mods .. ' helpclose'
+	    let s:did_open_help = v:true
