epub reading and converting

There are a lot of softwares to read and create epub books. I have tried some of them which were free. But for creating and reading epub books I felt comfortable with only a few of them.
For reading epub books in desktop, I found “Adobe digital edition” most convenient. You can create library and manage your epub books with it. But unfortunately it can not create epub format.
For epub creation there is another great software. That is “Calibre”. It is free also. You can easily download and install the software. I have converted some pdfs to epub and the output is good.
For reading epub format in my windows mobile the best free software I have tried is “Zulureader”.

Now come to Ubuntu. Go to Add/Remove option of applications and search for E-book reader. Select it and follow the instructions.
After installation the software can be run from

Application -> Office -> E-Book reader

That should do

Assigning a shortcut key to a program

Assigning a shortcut key to a program is handy. You can access the program with only one step. It is possible to assigning a shortcut key to a program in windows XP. That is in windows XP, any program can be launched using the keyboard by assigning a shortcut key to it.

For assigning a shortcut key to a program, at first you'll have to create a short cut of the program run file.

Program icon-> Right mouse button click -> Create a shortcut button.
Then right click on shortcut button -> Properties -> click on the box of "Shortcut key" and hit the desired button (for example- "Q") and click "Apply".
You should be done.

Now Alt+Ctrl+the key (Q in this case) will run the program.

After creating the short cut following description may also be useful ( found from http://digital-quest.blogspot.com/2007/09/assign-shortcut-key-for-any-program_28.html)

Right click the program to which you want to a shortcut key. In properties, under the shortcut tab, “shortcut key” is by default, “none”. Just click in the box and chose an alphanumeric key to be assigned as the shortcut key. Windows will assign [Ctrl] + [Alt] + [(alphanumeric key)] as the short cut key.
