1. A method comprising: receiving, by one or more processors, a first input indicating user activity that comprises a first edit to a document at a first position in the document in a document editing application executing on a computing device, wherein the document editing application is navigable among different partial views of the document, and the document editing application displays a frame element that indicates a position of a presently displayed partial view of the document with reference to an entirety of the document; and displaying, by the one or more processors, in response to the first input indicating the user activity that comprises the first edit to the document, a first marker, in or proximate to the frame element, indicating where the first position of user activity is located with reference to the entirety of the document, wherein the first marker is separate from the first edit to the document; receiving, by the one or more processors, a second input indicating user activity that comprises a second edit to the document at a second position in the document in the document editing application; displaying, in response to the second input indicating the user activity that comprises the second edit to the document, a second marker, in or proximate to the frame element, indicating where the second position of user activity is located with reference to the entirety of the document, wherein the second marker is separate from the second edit to the document and is visually distinct from the first marker, wherein the first marker and the second marker are different numbers, and wherein the numbers for the markers are modified as additional markers are added, such that a first number always represents a position of a most recent user activity, and a second number always represents a position of a second most recent user activity.

The method of claim 1 , wherein the first marker comprises a change in a color or a shade in or proximate to the frame element at a frame element position that corresponds to the first position, the method further comprising: receiving additional inputs indicating user activity at the first position of user activity in the document in the document editing application; and displaying, in response to the additional inputs indicating user activity at the first position of user activity, cumulative changes in the color or the shade in or proximate to the frame element at the frame element position that corresponds to the first position.
