Please support this feature since it is super-useful to mass-edit code. Often I:

• Perform a find to get a starting position of lines I want to mass edit
• Navigate to the beginning of each line by clicking home button
• Hold shift + end (or end twice) to select the entire lines
• Perform another find to get to where I need to be in each line -- This is not supported

This feature is supported in Sublime Text. I am trying to convert to using VS Code, but this could be one of those deal-breakers.

@scottpelak, i think this is already "in" VS Code. The "find all" + cursor at each occurrence is the biggest feature of ST3 that i use dozens of times every day.

Right now, i have found the `Change All Occurrences" via right click on any of the find results. This will then give me a cursor at every occurrence. i can move the cursor around to the beginning / end of a line ... etc

Hi @scottpelak,

I'm not immediately clear on your goal - why isn't your starting position where you need to be and how does this relate to the OP (i.e. "Find in selection")?

Hope to hear back

Cheers
