A lot of functions in Business Central can be reached with the use of keyboard shortcuts. This is good to know so you are able to use the system as efficient as possible.
Some of you may also have been effected by the browser trouble that Business Central experienced a couple of days ago. The effect was that some menu items were not visible but they could still be reached using the keyboard shortcuts.
Please refer to the keyboard shortcut page in Microsoft doc for a updated overview of all keyboard shortcuts in Business Central. There you will even find the keyboard shortcuts in a pdf file that you can print as a reference.
