I have tag name, X. I want to remap key C-] so that it remembers tag name in some variable b:tag. The I want some other mapping that will bring me to *next* definition of "last C-]ed" tag. The ":tnext" command already supports this and jumps to the next matching tag definition. You can use the following commands to browse through multiple matching tags: :tnext :tprevious :tfirst :tlast :tselect :tjump :ltag - Yegappan I thought the logic can be "check if we are already at some definition of tag b:tag". If we are, then just to the next definition. But maybe it's not needed, [to knwo whether we are at the definion", if the next-tag-def mapping will remember the definition number. Yes, in fact that's all that's needed. I think I have everything in palce to create the next-tag-definition mappnig. Yakov

In many cases (such as the Vim help tags files) it has a search command instead. But what was Yakov asking?

Yakov See my original reply to you: Vim already has "get to next/previous matching tag", :tn[ext] and :tN[ext] / :tp[revious] Best regards, Tony.
