The three most important keys on your Mac can be found to the left and right of the spacebar (for right and left handed use). Unfortunately these three keys seem to cause more confusion than any others.
Using the Option or Alt key on a Mac
There is a great deal of confusion over what Apple referrs to as the Option key. If you'are using a UK keyboard chances are this is called the Alt key so it's no wonder most people don't know where it is.
The Alt (aka Option) key can be found between Control and Command. It has an icon that looks like a slope and a dip with a line above it.
Chances are the first time you hear mention of Option you are following a tutorial and trying to fix something on your Mac. The Alt key is the one you use if you wish to select a boot partition when starting the computer, you also press it when typing certain characters on your keyboard, such as # (Alt-3) or ¢ (Alt-4).
Here's an overview of the hidden characters that you can type using Alt (the keys might be a bit different if you aren't using a UK keyboard as we are).
The Option key also enables you to enable the Save As option in Mac apps.
You may be wondering whether you can use the Alt key ctrl-alt-delete to shut down an unresponsive Mac. Force quitting on a Mac is slightly different to on a PC, here's how to ctrl-alt-delete on a Mac, aka Force Quit on a Mac.
How to type €, #, … and © on a Mac
- Alt-2 - Euro sign (€)
- Alt-3 - Hash sign (#) (Sometimes called the 'pound' sign)
- Alt-: - ellipsis (…)
- Alt-G – copyright ©
You can also use Alt/Option to do the following:
- Control-Alt-Command-Power Button - Quit all apps
- Alt-Shift-Command-Q - Log out of your user account on your Mac
- Alt-Delete - delete the word to the left of the curser
- Alt–Left Arrow - move the curser to the beginning of the previous word, add Shift to this to highlight the text
- Alt–Right Arrow - move the curser to the end of the next word, add Shift to this to highlight the text
- If you are selecting large sections of text, you can do so by moving the curser to the end of the section you wish to select and pressing Alt-Shift-Up Arrow until all the text is selected. (This only works in some apps).
- Similarly, Alt-Shift-Down Arrow lets you highlight the text below the curser
- Alt-Command-F will open the Find and Replace feature if your application has it
- Alt-Command-T will show or hide the toolbar
- Alt-Command-C is the key combo to use if you wish to copy a style, or copy the formatting settings to the clipboard
- And Alt-Command-V will paste those formatting settings onto the text you wish to change
- Alt-Shift-Command-V will paste and match style - so that the text you paste in has the same style as the text around it, rather
- than the style bought over from the place you copied it from
- Alt-Command-D will show or hide the Dock at the bottom of your screen
- In the Finder, Alt-Command-L is a handy shortcut to open the Downloads folder
- Also in the Finder, pressing Alt-Command-P will show the path so you can see the precise location of what you are looking at
- Alt-Command-S will show or hide the Sidebar in the Finder
- Alt-Command-N will start a new Smart Folder in the Finder

- To duplicate/copy an item in the Finder or on your Desktop, press Alt while dragging it.
- To create an Alias (a shortcut to a file) you press Alt and Command together while dragging the file from the location in the
- Finder to another location, an arrow sign will appear indicating that this is a link to the file rather than a copy of it
Using the Command key on a Mac
If you thought that the jumbling of Alt and Option was baffling, there's even more opportuity for confusion when it comes to the Command key. The Command key (cmd) has a legacy that leads to confusion - many older Mac users will refer to it as the Apple key, because in the past there used to be an Apple logo on it, but this logo stopped appearing a while ago when if was decided that there were a few too many Apple logos on Apple products.
The logo you will still find on this key looks like a squiggly square, or a four petalled flower. It was designed by Susan Kare for the original iMac (and based on the Scandinavian icon for place of interest).
The Command (cmd) key works in a similar way to the Control key on a PC. On a Mac you use the Command key where on a PC you would use Control (or Ctrl).
If you were wondering why Ctrl-B didn't make your text bold, chances are you were previously a PC user and didn't realise that Command is the new Control. You might find this useful: How to move from PC to Mac: Complete guide to switching to a Mac from a PC.

Press Command-Control-Space and by default you will see the Emoji characters. To see the Character Viewer, with special characters from any font on your Mac, click on the Character Viewer icon in the right corner of the window, or in the menu bar next to the time and date.

You can also search for any option using the Search field in the top-right. Enter a term like "cat" to find all the symbols that are cat-like.
The Character Viewer is placed permanently above all other windows, so you can continue typing in your app and view the Character Viewer on top of its document. You can switch between a small and large Character Viewer using the icon to the right of the Search Field.
It is also possible to add the Character Viewer as a Menu bar icon, this enables you to quickly access it from any app. Open System Preferences, choose Keyboard > Keyboard and select the Show Keyboard & Character Viewers in Menu Bar option.
