The Left Button Single and Double Clicks
Part of the Basic3 Skills Online Courses
Authored by

Hello! I'm "Lefty M. Button", a twin.
I have a few jobs to do. I am the master of
the left mouse button. You have to
left click something once
to tell me what you want done. If you
quickly left click
something twice, then I will do it for you. I
can even do a couple of things at the same time.
I am the "optic nerve" between you and your computer. Computers
have no way of knowing where
you are looking on its screen. I do that for you. Although
there are some things on this page that I could "do" they are limited.
First, if you just place the "pointer" anywhere on the screen,
(except for the darkred colored text
and the
Part of the Basic3 Skills Online Courses link) and
single left click there is nothing for me to do on this page.
The one thing I can do for you on this page, is to remove
the pop-up images you create using my twin, "Righty M. Button".
Oh yea! I do have something I can do,
but the author wants to wait and tell you in a moment. Hold me down
and "drag" me around. See what I found?
We will discuss
this "masking" later, so just single left click something else for now!
Things I can do:
I can ask you what to do.
Find and preform links.
"Cut", "Copy" and "Paste".
Do additional editorial jobs.
Manipulate computer files, and execute other Windows functions.
Textual Links:
"Links" can be textual, like
Click here.
Links, by default or by specific assignment, have colors
related to three conditions: On this page:
Links not visited are "blue".
Links that have
been visited are "Green".
If you "hover" the mouse pointer over a link
and press the left button, it will show as "Darkred".
Before you release your pressed left button, move the mouse pointer off the link.
It is common to see textual links underlined,
but your author prefers not to underline links. The underlining of links is a
browser parameter that can be set to remove the underlines.
Graphical Links:
A link could be a graphic, like "me". Here the author placed a "border" on my edges.
The three colors, again, indicating the conditions of the link, apply to the border colors.
Of course, the author need not place a "border" on my edges. The right image
has not had its "border =" parameter set to zero. The left image has had its
"border =" parameter set to zero. Graphic links are
not underlined as textual link may be. Both these images are
links to the "Graphical Links:" label.

Finding and Clicking Links:
One of the functions of the mouse, that is not
"button related", is the finding of Hypertext Links.
There are "entities" on most web pages that provide web addresses of other pages,
or other points on the same page.
Some of the "entities" below are links, and some are not.
You do not need to click anything below.
Just place the mouse pointer over each "object".
All "hypertext links" will change the mouse pointer image.
So will "graphic images" that are not links change the mouse pointer image.
The two alternate mouse images is dependent upon your browser's setting.
Click the two "up arrow" images below to illustrate the two alternative images.
