Multi-Commit Selection for Diff Operations

[biegacz1]

Is your feature request related to a problem? Please describe:
When working with git history in lazygit, I often need to analyze or share changes across multiple specific commits. Currently, I need to individually view or copy diffs for each commit separately. There's no way to copy diff of multiple commits.

Describe the solution you'd like:
I would like lazygit to support selecting multiple commits in the commits view and then:

1. Copy the combined diff of all selected commits to the clipboard
2. Open all selected commits in the configured difftool with a single command

Describe alternatives you've considered:

• Writing shell scripts that extract diffs for specific commit ranges
• Using git on the command line with commands like git difftool commit1..commit2, but this requires leaving lazygit

All of this is supported in the latest version, I do these things all the time. Which version are you using?

[biegacz1]

I use v0.48.0 and when I select range of commits then type y I get an info on the bottom that action doesn't support range, only single element.

[stefanhaller]

Ah ok. You need to press enter to go into the diff to see its files, then you can type y and get a menu to copy the diff of either the selected file or all files.

I guess we could improve this to also offer the menu in the commits list, but the diff option would really be the only one that would be enabled in the menu.

Oh I didn't know that I can do that that way, thanks!
