No, back button is not like undo. Back button takes you to the previous page you have opened. If there is no previous page or if you are at the first page, back button will not work because there is no page opened previously.
Undo :
It erases your current do, or current task.
If you are playing cards in computer, press undo, your last move of card will be cancelled.
If you are using it for a web browser like internet explorer, add a back button, then double click it and enter: webbrowser1.goback.
You can add a book mark to a page so you can easily come back to it later. Depending on what browser you have, there is a "bookmarks Bar" at the top where it will let you give your bookmarks a title and you can just click on the button. Basically it will give you a button to click on to easily return to a website that you like.
Just like any other browser, you'd need to have Adobe Flash or the ability to use the HTML5 player. Once on the video page, just hit the button in the video player that looks like a play button.
The button is the preview button. It is located in the toolbar up the top and it looks like a magnifying glass. When you click it you may be prompted to save the webpage you have been working on and when you save you can see your webpage in a web browser.

There's a button on the back which is like a hole but has a point in it , poke that with a pen and it'll reset.
Just hold the sleep/wake button and home button for about 10-15 seconds. Then release the sleep/wake button but keep the home button pressed for about 10 more seconds. Then release the home button and wait and it should come back as factory default, and just plug it into Itunes like if it were a new ipod. Beware this will eliminate any data you have on your Itouch. Back-up all data you have before doing this.
it is just like the ok button like any other phone
Just click the like button again
Use the refresh or reload button in your browser. It usually looks like an arrow that is coiled almost all the way into a circle.
Here's how you navigate between webpages: If you already know where your going, is to just type in the address that you want to go to. There are buttons on the browser like Back, Forward, Home, Reload, etc. Just under that is a box with some text in it. You can highlight that text and type in the address of the page that you want to go to. Just type it, and press [Enter]. If you're at a page, and you want to go back to the page you were just on before it, press the (Back) button. If you've gone back, and you want to go forwards, press the forward button.
