....and when you make an alias, there will be a little curved black arrow in the lower left corner of the icon. Say the name of the file or folder that you make the alias from is Pseudonym. The name of the alias will then be Pseudonym alais. Anytime you double click on Pseudonym alias, Pseudonym (the original) will open. You can change the name of Pseudonym alias to anything you want, say "Surname" or even your surname. Whenever you double click on Surname, Pseudonym will still open.
Of course the purpose of the alias is to place it somewhere more accessible to you than the original so that you don't have to go hunting for it. Once you've moved Pseudonym alias you can rename it to Pseudonym if you want. But you can't do that in the same folder as the original.
To answer your question, yes, if you want to access apps from the desktop creating an alias of the app on the desktop is the way to go.
I have to ask though, why keep apps on the desktop? How is that more convenient than the Dock? It's bad practice to use the desktop to store apps and documents. It's also just so... Windows...
I wasn't sure if the dock has a max limit on the amount of apps & docs it can fit, does it? what happens when it reaches all the way to the ends of the screen? as I would prefer to keep all of my app shortcuts in the dock. & pardon the windows habit, I am just coming from windows, just got my new mac laptop this week.
what about the set of apps at the bottom of the dock that are preinstalled when one gets a mac? were alias's made of them & placed in the dock?
