How do I preview a fuzzy tag match in the preview window without immediately switching buffers?

Explanation

When a symbol name is ambiguous, jumping directly with :tag can bounce you around the codebase and disrupt your working context. :ptjump /{pattern} searches the tags stack with a pattern match and opens the selected hit in the preview window, so you can inspect candidates before committing to a full navigation jump. This is a strong workflow for large projects where many functions share prefixes or overload-like naming conventions.

How it works

• :ptjump combines tag search behavior with preview-window display
• /{pattern} lets you search tags by pattern rather than requiring an exact tag name
• The result opens in the preview window, keeping your current editing window focused
• You can scan definition details, then either close the preview or jump more deliberately with tag commands

Example

You are on a call site and want the right parse_* implementation without losing your spot.

:ptjump /parse_

Vim opens a matching tag target in preview, while your cursor stays in the original window.

Current window: parser_test.go (cursor unchanged)
Preview window: parser_impl.go at parse_config

You inspect quickly, then decide whether to continue, refine the pattern, or perform a full tag jump.

Tips

• Use <C-w>P to move into the preview window only when you actually need to edit there.
• Combine with :ptnext / :ptprevious to cycle previewed tag matches.
• Keep :set previewheight= tuned so preview does not crowd your main editing pane.
