Support * to search for the word under the cursor in copy mode

[sinharaksh1t]

When migrating from tmux, I miss pressing * (Shift+8) in copy mode to search for the word under the cursor, as in Vim and tmux vi copy mode.

In Herdr 0.9.5, I enter copy mode with prefix + [, move onto a word, and press *; no search starts. I can use / and type the word manually, but this interrupts a frequent workflow when navigating repeated identifiers, errors, and log output.

Could Herdr support * to search forward for the word under the copy-mode cursor, with n/N to repeat the search?

I searched open and closed issues and found related requests (#1230 for / and ?, and #970 for word motions), but no existing request specifically for *.
