I would like to use notepad++ like vim split open in horizontal mode.
Opening files in vertical mode can be done by move file to other view. I need to open files in vertical. Is there any plugin available out.
Open a file to the other view, then rightclick the seperator bar and choose rotate. It will go from horizontal to vertical mode, and back again on another rotate command.
ctrl-w s will split the screen into 2 parts (windows), one above the other. You can switch windows with ctrl-w ctrl-w.
Read more info with :help window ( :help also opens a new window to display the help info :-)
