In standard Emacs, pressing C-x 3 will call function split-window-right to split the current window into two identical windows. Sometimes I want to get more than two windows, so I wrote this little function:

It calls split-window-right multiple times to get multiple new windows and finally calls balance-window to adjust the sizes of all windows. eval this function, then you could press M-x wenshan-split-window-vertical (thanks to the auto-completion functionality, you won’t need to type all these characters) to call it.
