Tired of waiting for a never-ending Access loop to finish, just so you can realize you needed to hit cancel three minutes ago? Let's talk about a simple way to let your users abort a running process with the keyboard - no more clunky checkboxes, no frantic clicking, and (most importantly) no forced shutdowns required. The Escape key can be your new "panic button." Here's how and why you should set this up in your own databases.

When you create long-running operations - like sending out 10,000 emails in a batch - your users might suddenly realize they need to stop the process. If you don't give them a way to abort gracefully, their options are ugly: force-quit Access, cross their fingers, or just stare in silent dread. Historically, maybe you added a hidden checkbox or "abort" button, but those solutions aren't very friendly (especially to keyboard-focused users or anyone with a penchant for hitting Escape in emergencies). Let's teach your database to listen to the Escape key and stop those runaway loops on command.
Let's start with the basic approach: tying an on-form "Cancel" button to the keyboard. Access forms have a handy built-in feature: any command button set to Cancel = Yes automatically responds to the Escape key. So, if you stick a "Cancel" button on your form and connect it to your abort logic, your users can smash Escape and halt the process without fumbling for the mouse. Just make sure you wire up your loop so it checks regularly for an abort request.
But here's a power tip: don't forget about DoEvents. This little command sprinkled inside your loop is what lets Access recognize outside actions - like button clicks or keys being pressed. Without DoEvents, your process hogs the show and ignores everything else, giving the illusion that Access has frozen. So, always include DoEvents (often inside a status update function) during each loop iteration.
Now, for those who want an even cleaner keyboard solution, you can skip the "Cancel" button entirely and work directly with keyboard events. Here's how:
1. Open your form's properties and set Key Preview to Yes. This tells Access your form wants first dibs on all keyboard activity, regardless of which control is active.
2. In the form's On Key Down event, check for the Escape key by testing If KeyCode = vbKeyEscape.
3. When Escape is pressed, set your abort variable (maybe Abort = True) and swallow the key (KeyCode = 0). For bonus feedback, update the status display so users know you heard them.
This approach is more "global" to the form, so you don't need a visible user control at all. As long as your loop keeps checking for Abort = True (don't forget that DoEvents!), users can bail out instantly, just by hitting Escape.
Keep in mind, the responsiveness depends on how often you check for that abort signal. If your loop has a long delay (for example, sleeping a full second between iterations), the cancel might feel sluggish. For faster response, either shorten the sleep interval or check for aborts in smaller increments inside your main loop.
What about taking this further, so you can trap Escape key presses throughout your entire database, not just on a single form? That's possible too with a tiny bit more advanced VBA, and I cover that in my member-exclusive extended tutorials. (Not a member? Time to consider an upgrade… there's a code vault packed full of goodies over on my website!)
Bottom line: making the Escape key your abort switch gives your users a fast, intuitive way to kill a stuck process - and it makes your applications feel a lot more professional and user-friendly. I'm a keyboard person myself, so this kind of improvement just feels natural.
