WiscChat (Psi) - Can I Use a Different Key Combination to Send Chat Messages
By default, Psi uses the 'Enter' key to send a chat message within the chat window. Some users may want to change this setting to prevent accidentally sending passwords or other private information.
To make this change, uncheck "Enter key sends chat messages" within the Options | Chat preferences. Disabling this options will automatically assign Ctrl-Enter as the key combination to send a message.
If you want to assign a custom key combination, use the Options | Shortcuts preferences.
