Subject: [PATCH] Add 'd'elete keybinding to search and show views
Date: Wed, 21 Apr 2010 16:16:03 -0700
Message-Id: <1271891763-10757-2-git-send-email-hohndel@infradead.org>
In-Reply-To: <1271891763-10757-1-git-send-email-hohndel@infradead.org>
References: <1271891763-10757-1-git-send-email-hohndel@infradead.org>
Precedence: list

This is a variation of the 'a'rchive binding - it additionally sets
the "deleted" tag (which notmuchsync uses to trigger pruning of files)
