Hello MacRumors and Mac friends. The keyboard shortcut for page down or page up is fn - up arrow key (or down arrow key) but what's the keyboard shortcut for Home and End (to get to either to the topmost or to the bottomost of the page or a document)? Thank you. Stay safe God bless...

I cannot understand the pixel sizes of certain pics that are published in fb, simply because when resizing the window the pics get larger and i cannot measure them. How can i found out what their sizes should be in the first place so i can upload them without being to small or large?
