REORDERING TAB PAGES:
:tabm[ove] [N] *:tabm* *:tabmove*
+:[N]tabm[ove]
Move the current tab page to after tab page N. Use zero to
make the current tab page the first one. Without N the tab
page is made the last one.
+:tabm[ove] +[N]
+:tabm[ove] -[N]
+ Move the current tab page N places to the right (with +) or to
+ the left (with -).
+
+Note that although it is possible to move a tab behind the N-th one by using
+:Ntabmove, it is impossible to move it by N places by using :+Ntabmove. For
+clarification what +N means in this context see |[range]|.
