I would like to share few easiest & short cut ways. 
This time I came up with this blog which is not too technical 
but still
I hope you guys will find this stuff interesting. 
Here are the bits and pieces..
Bit -1 : Adding your favorite to FAVORITES
Log on to system. You will find SAP Easy access screen.
Right click on FAVORITES and select ADD OTHER OBJECTS
Select WEB ADDRESS or FILE
Enter the Text and URL you like as shown below
This will be added under the FAVORITES folder
Similarly we can add Tcodes, Reports, Company email urls etc.
Bit -2 : Info source Overview option for a DSO or an Info cube
Select a DSO or Info cube and Right click on it. Choose “Info source Overview”.
It will display all the loadable Master Attr data sources, Text data sources, Hierarchy data source and Transaction data sources for this data target. Also displays the Last loaded Request.
Bit -3 : User Profile settings
Tcodes: SU3 and click on DEFAULTS tab.
Here you can change the Decimal notation, Date format, Time format and Personal Time zone
Bit -4 : Creating a shortcut on the desktop for a Tcode or report
If you want to create a shortcut on the desktop for a transaction then
Go to that particular Tcode. Ex: SE11
Click on Customizing local Layout ( Alt + F12) and select Create shortcut.
Bit -5 : Adding the objects which you are working currently under FAVORITES in RSA1
Go to RSA1. Select the objects which you’re currently working on. Drag and drop them on FAVORITES under Modeling as shown below.
Now the objects will be available under FAVORITES so that we can easily access.
After the work is done you can remove those and can add the new ones.
Bit -6 : Delete the transaction code in the command bar
This is my favorite one. Sometimes I wanted to hide the transactions which were used
. I had asked many persons how to clear the history of the Tcodes from the command bar. After many trails, I found one way of doing it.
How to delete the Tcodes entered in the Command bar.
Click on the drop down beside the command bar and select the Tcode which you wanted to delete by up/down arrows using the keyboard. The tcode should appear in the command bar and selected in the dropdown then click on delete. It clears the Tcodes history which was used.
Hope you find these bits and pieces interesting and useful
