Abstract: Systems and methods for displaying annotations associated with an electronic document. One system includes an electronic computing device with an electronic processor configured to display a user interface on a display device. The user interface includes a canvas displaying a first subset of content included in the electronic document and a region scrollable independent from the canvas. The electronic processor is also configured to display a first plurality of annotations in the region. Each of the first plurality of annotations are associated with an anchor within the first subset of the content and displayed spaced within the region in at least one dimension based on spacing of the associated anchors. The electronic processor is further configured to change the region to display a second plurality of annotations in the region in response to changing the canvas to display a second subset of the content included in the electronic document.

Abstract: An enhanced charging handle for a firearm which has an elongated shaft having a forward end and a rear end. The forward end is formed into a bolt hook that engages the bolt carrier group within the firearm. Attached to the rear end is a latching assembly comprising an L-shaped latch, a vertical lever, and a compression spring where the latch and vertical lever are pivotably attached to the rear end. The latch and vertical lever operate together such that pivoting the vertical lever disengages the latch from the upper receiver of a firearm allowing the charging handle to be moved freely by the user independent of the upper receiver of the firearm.
