VimSuspend When the Vim instance is suspended. Only when
CTRL-Z was typed inside Vim, not when the
SIGSTOP or SIGTSTP signal was sent to Vim.
+ *WinClosed*
+ WinClosed After closing a window. The pattern is
+ matched against the |window-ID|. Both
+ <amatch> and <afile> are set to the
+ |window-ID|. Non-recursive (event cannot
+ trigger itself).
*WinEnter*
WinEnter After entering another window. Not done for
the first window, when Vim has just started.
