+1.
+brew install etags
+
+When you changes root directories you need to update it.  So if you do it in the ~ directory you shouldn't need to change it.
+
+find . -type f -iname "*.[cppc]" | xargs etags -a //this installs what we need for etags
+ctags -R *
+M-. <RET>
+C-u M-.
+
+every new function, class, etc.
+
+cscope -R
+You need to rerun it when you add a new file.
+
+vim file.name
+CTRL-\ s
+CTRL-D //to exit
+
+ctags allows you to jump from function calls to the definitions as well as completion.
+cscope allows to both jump from function calls to definitions and jumps to functions calls.  Jumps to the file that the function is found.
+ctags is fast and easy to set up while cscope is great for bigger and file types that aren't known.
+They are both good in their own right.
+
+
+2.
+multiple cursors
+(command mode) C^n until all highlighted then insert mode
+
+Surround
+(command mode) ysiw(some sort of surround here"
+
+
+3.
+Preferences -> Settings -> remove vintage mode
