Is there an arrow app, dpad or other solution for moving the cursor beside my stubby finger? One of my few frustrations with the NC as a tablet is moving back or forward (up or down) precisely in a line of text such as a web address, email or other text document. Is there a solution besides my finger or a keyboard app with arrows? I have found a couple of nonstandard keyboard apps that have arrows, but have come up empty searching the marketplace for an arrow app. Thanks.
