Emoticons or other images are inserted into text messages during chat sessions without leaving the chat session by entering an input sequence onto an input area of a touchscreen on an electronic device, thereby causing an emoticon library to be presented to a user. The user selects an emoticon, and the emoticon library either closes automatically or closes after the user enters a closing input sequence. The opening and closing input sequences are, for example, any combination of swipes and taps along or on the input area. Users are also able to add content to chat sessions and generate mood messages to chat sessions.
