AceType is a special AceText feature that enables you to quickly paste a clip into an application, and continue working with that application after pasting. The default hotkey is Win+Alt+A. When you press this hotkey when working with an application other than AceText, AceText will pop up. If you like to use the mouse, right-click on the AceText tray icon and select AceType from the menu. If the icon is not visible, you need to start AceText first.
You will notice that after activating AceType, the AceText window looks a bit different. Above the list with clips in the collection, a highlighted AceType field appears. Type in the AceType abbreviation of the clip you want. As you type in the abbreviation, the list of clips in the collection is filtered. It will only show clips that have an abbreviation with the same characters as the ones you typed. As soon as you activate AceType, the labels of the clips in the list will be prefixed with their abbreviations. Clips that do not have an abbreviation will be hidden. If you forgot the exact abbreviation of a clip, you can easily look it up. While typing the abbreviation, you can press Ctrl+Arrow Up or Ctrl+Arrow Down on the keyboard to select one of the clips in the list, without typing in (the remainder of) its abbreviation.
Press the Enter key on the keyboard to confirm the selection. If the clip contains parameters, AceText will substitute them and prompt if needed. The clip is then pasted directly into the application that was active when you initiated AceType. Press the Escape key to cancel AceType. Either way, AceText will bring to front the application that was active when you initiated AcePaste, so you can continue working straight away.
Obviously, AceType is only useful if you have previously assigned memorable abbreviations to your clips. This way, you can easily and even blindly insert standard chunks of texts while typing. E.g. when replying to email, instead of typing the same "thank you for your purchase" phrase over and over again, store the phrase into a clip with an abbreviation of "ty". Then you can instantly add the phrase while typing. Just press Win+Alt+A, T, Y, Enter and continue typing the rest of the email. Besides saving you the time to type in the same phrase, AceType enables you to make the phrase much lengthier or polished. Since you need to type it only once into AceText, you can spend 5 minutes writing a very nice thank you message, and then instantly replicate it whenever you answer an email message. Your correspondents will be impressed.
By default, AceText will try to paste into the target application by placing the clip on the clipboard and simulating the Ctrl+V key combination. If you want to use AceType with an application that pastes differently, or can only accept keyboard input, you can configure that application in the Applications Preferences.
