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:

Airdroid – great way to manage your Android via your computer

airdroid-app-screenHere’s a great way to manage, manipulate and use your Android smartphone via your PC, simply by using your local wireless connection.

It’s called Airdroid, and consists of an App that you install on your Android device, and then a web link, which you use on your PC. (There is also a desktop App available, but I prefer the web link method.)

On the left is a screenshot of the app running on my Samsung Note 4.

Once you have set-up the app on your phone, and made the initial connection, no further installation is necessary; it all works from a link in your browser.




In the screenshot on the right, you can see how Airdroid Web appears, in your desktop browser. The icons and overlays can all be arranged according to your liking. In this view, you can see how I have opened the photos section, to view the photos on my smartphone.

There’s a whole lot more to Airdroid, which is fully explained in the online help, also accessed from the interface.

The best place to start is the online FAQ:

Airdroid – FAQ and help guide

Once you’ve got it installed, checkout the vast help resources from this link:

Airdroid: List of Help resources

Give it a go; it’s a simple way to manage your Android to your computer without a wire.

WinKey Tips – WinKey + TAB

A really cool use of WinKey is to combine it with the TAB key. Pressing WinKey + TAB displays a static overview of all your open Windows, allowing you to select the one you need with your mouse, or tapping it, on a touchscreen.winkey-tab-screen






Compare this with ALT + TAB, which sequentially switches between open Windows, and requires a bit of finger dexterity to release the WinKey at the appropriate time!




Learn to ALT + TAB

Switching between running programs – use Alt + Tab

Today’s quick tip is to get into the habit of switching between your open Windows.
When you’ve got several applications and programs running – perhaps a browser or two, a word processor document, and your Email client, it can seem laborious to move the mouse down to the taskbar or wherever, and bring-up the one you want.  Well, you don’t have to – there is a much easier way to switch between running programs:
Hold down the ALT key and, while holding it down, tap the TAB key (its usually above Caps Lock)
You will see your running apps in scaled-down form on your screen, with a highlight/border swapping between them each time you tap the TAB key.
To switch to one of the running programs, simply RELEASE the ALT key when the highlight is on the program you want to switch to. It’s really easy – try it!alt-tab

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.

Copy and Paste, Cut and Paste……. and All that!


Recently, I’ve been sharing the keyboard shortcuts in Windows that I find particularly useful, are easy to remember and, most importantly, are used frequently.

So for today, I thought I’d encourage you to learn 4 essential shortcuts as mentioned above; they are particularly useful when editing documents:

Copy and Paste

CTRL + C    copies a highlighted word, phrase, paragraph etc to the clipboard, (a special temporary storage area in the computer’s memory).

CTRL + V    pastes the copied item into the location you desire.

How to remember:

C is the first letter of Copy

V for paste – see it as a downward pointing arrow

Cut and Paste

CTRL + X    cuts a highlighted item

CTRL + V    pastes (i.e. moves) that CUT item to the new location

How to remember:

X looks rather like an open pair of scissors

V looks like a downward arrow


CTRL + A selects All of the current document, item, picture.  Very handy, prior to doing one of the above operations!

How to remember:

A is the first letter of All

WinKey tips – continued


WinKey + left or right arrow key (← →) enables you to “snap” the current Window to one side of your screen, thus using only 50% of your workspace. The really clever thing about this is that, if you then select another open Window, perhaps from your taskbar or desktop, that other Window will “snap” into place alongside its neighbour!

WinKey + up arrow (↑), depending on how the current Window is sized, enables you to quickly maximise your current window, or bring it out of the taskbar.

WinKey + down arrow (↓) will either shrink the current Window to the taskbar, or shrink it to the last known size.  To get it back, see WinKey + up Arrow

WinKey + S opens the Search utility

WinKey + I opens the Settings menu

There are other WinKey shortcuts, but these are the most useful, IMHO.
