edit : in this mode u can change and save the changes made by u. view : in this mode u can change but u can't save the changes made by u. browse : in this mode u can't even change the text.
Also what i came to know is that when u r viwewing a dataset in view mode,then the whole dataset(say of 10000 lines) is sent to the main memory. But with browse mode,only the page that u r viewing is in the main memory(like 17-18 records on single page) and rest of the records are in buffer.Only after pressing pagedown u r calling next records into the main memory from buffer.
