One little known fact about our soapbox platform is that you can actually right click in the editor window to get shortcuts to many commonly used WYSIWYG tools.
You'll see by right clicking that many great features are available, including the paste functions and the insert file, insert media, insert table, insert template, and insert images buttons.
Additionally, once you've added an image, file, or table, you'll see that when you right click on one of these items, you will get a different list of available functions. These right click menus will provide commonly used functions related to the element in the editor that you've clicked.
Give it a shot, you may save some time by utilizing these right click short cuts.
