In vimperator I often have 20+ tabs open. To get a list of my tabs I press "B" which shows the buffer/tab numbers.
So I want to do something like :3,5bd to delete tabs 3 to 5. Is that possible?
You can read about closing tabs in Vimperator in the Vimperator's help file.
As it comes to the actual question, I don't think you can do exactly that - with that specific syntax, at least. However, to close tabs 3 through 5 is possible with 3gt 3d
.
So, first you have to change to the first tab to be closed and do some math yourself (how many tabs you want to close: 5-3 + 1 = 3).
You may also use :tabgroups
command to group tabs and then remove whole group.
You can find out about tabgroups
using :help tabgroups
To remove tabs by pattern you can use:
:bd "<wow I have 200 tabs open with oracle support>"
:bd support
