Open the summary window and jump to the "currently edited" file?

[intelfx]

Is there a shorthand to open the fugitive summary window (i.e., :G) and simultaneously have the cursor jump to the entry for the "current" file?

The "current file", specifically, is the file whose buffer was active immediately before the fugitive summary window was opened/focused.

There's nothing for this. Note the "current file" may appear both in the staged and unstaged sections, so this would be an ambiguous operation.
