When to use PDF files







A question I often get asked by customers is: What is a PDF file, and when is it used?

I frequently CREATE my invoices and receipts in .docx format, and then SAVE A COPY in PDF format for emailing to my clients; they are more likely to be able to view a PDF file.

The following article, published yesterday at Makeuseof, gives a great explanation:

Where are my Photos on my Mac?

How to find your original photographs and images when using the Photos app on a Mac


If you use the Photos app on your Mac to organize and view your photographs and images that are being kept on your Mac, you may have wondered “Where are those original photographs being stored?”

Well, it turns out that the answer is quite complicated, and will depend upon how you let the Photos App manage your photographs library.

In the following example, I have already started using Photos; I simply imported some spare photographs directly into the Photos App, to experiment.

Please realise that the way in which the “Photos App” stores your images on your Mac is deliberately complicated and for a very good reason: it’s to discourage you from playing around with the original copies of your precious photos, as you may end up accidentally deleting them!

So, with that disclaimer and warning in mind, I will show you in this video how you can, if you wish, discover the actual location of your original photos on your Mac:

Quick zoom shortcuts

How to zoom in and zoom out on a web page

Today’s quick tip is for those awkward moments when you can’t quite see part of a website you are viewing; perhaps a form has disappeared off the bottom of the screen, or some text or image is the wrong size to view easily.

(These tips can work in other applications as well, but I find it most reliable in browsers.)

To Zoom IN:

CTRL with +  


Hold down CTRL key and tap the plus key (usually located on your top row of standard keys – number keys – at the right. If you’ve got a numerical keyboard as well, you can also use the plus button on there, as long as Num Lock is on – (otherwise you may activate the Windows magnifier!)

To Zoom OUT

CTRL with 


Hold down CTRL key and tap the minus key (again, usually located on the top row of standard keys – number keys – at the right. If you’ve got a numerical keyboard as well, you can also use the subtract button on there, as long as Num Lock is on.

To reset the Zoom:

CTRL + 0 (zero)


You can usually reset the view in a browser this way, but be prepared to use the other two methods if it doesn’t work.

Extra power-user tip:

If you are using a mouse that has a mouse-wheel, you can hold down CTRL key and turn the mouse-wheel forward and back to zoom in and out!

Apple users

Substitute Command  for CTRL in the above tips.

Learn how to UNDO your last action in Windows and Mac OS

It’s the weekend, so just one simple tip to learn today!

I have found that one of the most useful keyboard shortcuts to know about is UNDO.

In Windows:   CTRL + Z



In Mac OS:      ⌘CMD + Z



Note how convenient these are; the Z key is very close to CTRL or CMD.

Using a keyboard shortcut in this instance is usually quicker and easier than locating the “undo” icon (if it exists!) in the app or program.

An example of when I use this shortcut:

Say I’m in the Windows File Explorer and I perform an unintended action with a file; perhaps I accidentally delete a file, or a folder. I realise my mistake, press CTRL + Z and the action is undone – phew!

Try this shortcut out to see how helpful it is: it may not work in EVERY app – just see what you can do!
