From 95ac9b3b585d20df116c5bea1511d9eb5758ac81 Mon Sep 17 00:00:00 2001 From: Benjamin Poirier Date: Thu, 23 Aug 2012 14:55:08 -0400 Subject: [PATCH] menuconfig: Assign jump keys per-page instead of globally At the moment, keys 1-9 are assigned to the first 9 search results. This patch makes them assigned to the first 9 results per-page instead. We are much less likely to run out of keys that way.
