What you are trying to achieve is not difficult, but the task is not trivial. It's a real scripting project. I don't think you will find too many volunteers!
 
However, I can tell you some of the steps you are likely to need if you try to do it yourself:
 
Type Text Control F // Open the Find dialog
Wait 200 milliseconds
Type Text <metadata>
Type Text Enter
Type Text Escape // Close the Find dialog
Wait 200 ms
Type Text <Left arrow> // Turn off selection
Type Text Shift Control Home // Select to start
Paste Clipboard
Wait 500 ms
Type Text Control s // Save
Wait 2000 ms
Type Text Alt F4 // Close the document
Wait 3000 ms
Activate XXXX // Make sure Windows Explorer is focused
Type Text <Down arrow> // Go to next file in Windows Explorer

Click the "A" icon to modify the Accelerator...
 

Macro Express can detect controls in some programs, but not in browsers.
 
However, there are ways to navigate to controls via Macro Express without clicking on x, y coordinates. One approach is to search for unique text near the target, and then either Tab or Shift Tab to the desired control. In pseudo code:
 
Type {Control}f ' Find on the page. In some (most?) browsers, F3 does the same thing.
Delay 100 ms
Type Surname:
Type {Enter}
Delay 100 ms
Type {Escape} ' Cancel the search
Delay 100 ms
Type {Tab}{Tab} ' Tab to the desired field or control
 
You will need to play with delays and target text to get this to work reliably.

Maybe something like this?
Variable Set Integer %N1% to 0 Repeat Until %T1% Equals "" // Body of Repeat Loop Variable Modify Integer %N1%: Increment End Repeat // Check the value of %N1%, and decide what to do with it. Switch( %N1% ) Case: 0 // Do this if %N1% = 0 End Case Case: 1 // Do this if %N1% = 1 End Case Case: 2 // Do this if %N1% = 2 End Case Default Case // Do this if %N1% = 3 or more End Case End Switch
