Why does ESC speed up VBA operation in Excel under certain circumstances?
I have just experienced this, and I know there are quite a few references to the phenomenon on the web, so it’s not just me, but no-one has actually answered it. The normal result of pressing ES...
I would guess that Roy Brown, after 2 1/2 years, is probably not still reading these posts.
There is a feature in VBA called "EnableCancelKey".
FWIW, the following is from the Excel help file...
| Excel Developer Reference |
| Application.EnableCancelKey Property |
| Controls how Microsoft Excel handles CTRL+BREAK (or ESC or COMMAND+PERIOD) user interruptions to the running procedure. Read/write XlEnableCancelKey. |
| Syntax |
| Application.EnableCancelKey |
| Remarks |
| XlEnableCancelKey can be one of these XlEnableCancelKey constants. |
| xlDisabled. Cancel key trapping is completely disabled. |
| xlErrorHandler. The interrupt is sent to the running procedure as an error, trappable by an error handler set up with an On Error GoTo statement. The trappable error code is 18. |
| xlInterrupt. The current procedure is interrupted, and the user can debug or end the procedure. |
| Use this property very carefully. If you use xlDisabled, there's no way to interrupt a runaway loop or other non – self-terminating code. Likewise, if you use xlErrorHandler but your error handler always returns using the Resume statement, there's no way to stop runaway code. |
| The EnableCancelKey property is always reset to xlInterrupt whenever Microsoft Excel returns to the idle state and there's no code running. To trap or disable cancellation in your procedure, you must explicitly change the EnableCancelKey property every time the procedure is called. |

Quite right, I wasn’t, but I got an email from Microsoft alerting me.
So thanks for your answers.
Fortunately I haven’t needed to be waiting for them (grin)
