Editor Functions > Auto-Correction

Auto Correction

Auto correction automatically corrects any typo and spelling errors, if the auto correction option is turned on. For example, if "teh" is typed followed by a space, it will automatically be corrected to "the". You can use this to create your own abbreviations of text you frequently type. For example, if you set up your own auto correction to have "si" replace with "SELECT INTO".

Auto correction entries are user-defined and can be modified in the Preferences window.

To open the Auto Correction window

  1. Click Preferences image\B_Preferences.gif.

  2. Select the Editor tab.

  3. Under the Editing section, the Auto correction checkbox is used to enable auto correction. By default, this option is selected.

  4. To modify the auto correction entries, click the corresponding image\B_Ellipse.gif button to open the Auto Correction Settings window.

Available auto correction entries are listed on the list-box. Each entry has a REPLACE text (the original text typed) and WITH text (the replacement text).

Action keys are the keystrokes that activate the auto correction. When you type the REPLACE text and follow it by any action key, the replacement takes place. No whitespaces are needed to separate each action key. By default, the action keys are ";,:=[]\n\t\s" representing the following:
