skipstone-1.0.0-alt2 It seems that Shift-Ins switches to the previous tab. How to reproduce: (Actually, I try to paste something by pressing Shift-Ins. So, first open some text, select a region, press Ctrl-Ins to "copy" it (into the "clipboard").) Then open a new tab (Alt-N, well... I'm used to Ctrl-T, but it's tolerable), switch to the new tab, go to say, https://bugzilla.altlinux.org, click on the input field for "Search", and try to paste: press Shift-Ins. Instead of pasting, the browser switches to the previous tab. It's quite unexpected and irritating. Other browsers accept Shift-Ins well. I use icewm.
I don't really use this package (as already mentioned); may I respectfully suggest passing maintainership to you as obviously the more interested person?
Fixed with 1.0.1-alt2 @webkit; see also Settings > Switch to tabbed view.
