Sometimes, you may have your browser in Windowed mode and you may not be able to see specific options on screen, like the small black Actions link to the right of your filings in the Filing History.
You can maximize your browser window to Fullscreen mode so it shows you more of the website.
To go into Fullscreen mode, you can double-click the top bar of your browser (above the Address Bar).
Each browser also has a square button at the top right corner of their top bar that can be used to maximize the browser window or return it to a shrinked-down mode.
Google Chrome
Mozilla Firefox
Microsoft Edge
Apple Safari
On Apple Safari, the Maximize button is on the upper left corner of the browser, not on the upper right as with other browsers.
