From 10b045c29a3a1f35ecf8181b567587bd092e1290 Mon Sep 17 00:00:00 2001 From: "Tu, Do" Date: Sat, 30 Aug 2014 23:56:06 +0700 Subject: [PATCH] Allow enable/disable global helm key bindings Since some users prefer using default Prelude commands, a new global mode is defined: prelude-global-helm-mode. When activate, Helm binds some global key bindings to its own commands. When deactivate, Helm removes the bindings and Prelude uses the default bindings. --- README.md | 32 +++++++++++++++-- modules/prelude-helm.el | 78 +++++++++++++++++++++++++---------------- 2 files changed, 77 insertions(+), 33 deletions(-) diff --git a/README.md b/README.md index 5e5fc57..eaad200 100644 --- a/README.md +++ b/README.md @@ -372,9 +372,35 @@ If you ever forget any of Projectile's keybindings just do a: Helm is setup according to this guide: [A Package in a league of its own: Helm](http://tuhdo.github.io/helm-intro.html). -You can learn Helm usage and key bindings following the guide.
