Abstract: A method for operating a computer device incorporating a touch screen is provided. The method includes pre-defining a first pointing device command and a second pointing device command, which are not related to directional pointing control, in the computer device. In response to a first touch, the touch screen generates a first touch signal. The first pointing device invokes a command in response to the first touch signal. In response to a second touch different from the first touch, the touch screen generates a second touch signal. The second pointing device command is invokes in response to the second touch signal.

Abstract: A method for inserting attachments into an electronic message is provided. The method may include searching a keyword database to determine if a content of the electronic message includes a keyword, a key phrase, or a key sentence defined in the keyword database. The method may also include applying a condition to a file database, if the determination is affirmative, so as to search for at least a candidate item. The candidate item may be presented in a menu to the user. The method may further include enabling, in response to the user's confirmation of the candidate item, the confirmed candidate item to be inserted into the electronic message automatically to become an attachment thereto.

Abstract: A task item can be stored in a collaboration database, wherein the collaboration database able to be accessed by a communication module and a task management tool, which both run on a client. The communication module can be able to access a communication server that provides a communication service to the client. The task management tool can be able to access a collaboration server that provides a collaboration service to the client. A collaboration item can be established that contains a task identifier associating with the task item and a collaboration identifier associating with contact information. The communication module running in a client can be called according to the contact information of the collaboration database. The task item can be displayed within a user interface of a communication application via the communication module.
