Today's TechHelp tutorial from Access Learning Zone addresses a common issue when using arrow keys to navigate through continuous forms in Microsoft Access. Normally, you can use these keys to move up, down, left, and right between different records. However, there might be instances when you do not want this behavior, such as when editing a long text box.
This question comes from Dylan in Lombard, Illinois, who is one of my platinum members. Dylan has been using the technique I demonstrated for navigating continuous forms using the keyboard in my extended video. It works well until he clicks into a multi-line text box in the footer meant for customer notes. Using the arrow keys there unintentionally moves him to the previous or next record, which is not the desired outcome. Dylan wants to know if there's a way to disable arrow key navigation when editing this particular field.
Yes, Dylan, it can be done. Let's revisit what my original video covered and then address how to resolve your issue.
In the previous video, I showed how to move between records using the keyboard rather than the mouse by creating "Previous" and "Next" buttons with shortcuts. However, to navigate using arrow keys, you need to use VBA programming. For those who haven't watched this video, I suggest doing so as it provides a great foundation for VBA programming essential for this tutorial.
First, you should know that you can use Tab or Shift+Tab to move between fields, or configure the arrow keys for navigation. To set this up in Access, you go to File Options, then Client Settings. Here, an option labeled Continuous Form Record Navigation Keys allows you to use the arrow keys. Although convenient, this setting affects all continuous forms in your database.
To achieve this behavior selectively, you need some VBA code. Start by opening your form in Design View. In the Form Properties, set Key Preview to Yes. This ensures that the form intercepts keystrokes before they reach the fields.
Next, focus on the Key Down event in the Form Properties under Events. This event will capture each keystroke and allow you to implement your logic. In the Key Down event, you can check for specific keys, such as the down or up arrows, using VBA constants.
For example, if the pressed key code corresponds to the down arrow, you use the command to go to the next record. Similarly, for the up arrow, the command will take you to the previous record. To handle potential errors when moving beyond the last record, you include simple error handling in your code.
Now, to address Dylan's specific issue, you need to check if the active control is the notes field and skip the key handling logic if true. This way, arrow keys won't move to another record while editing the notes field. You can accomplish this by adding a conditional statement at the beginning of the Key Down event code to exit the subroutine if the active control is the notes field.
And that's it! Save your changes, compile the code, and test it out. You should now be able to navigate using arrow keys without affecting other fields, specifically the notes field, where arrow keys are reserved for text navigation.
