Find and replace only in one cell

I would like to "find" and "replace all" in only one cell. Is this possible? For instance if I have an expression common to many cells, and I want to avoid having to replace it also in other cells, how would I "find &replace all" it without having to worry about other cells?

Is there a way to add a button on ctr+F panel?

• The cheapest solution is to copy the cell to another notebook :) . I think you can make the question a bit more specific, for example, what do you need? A function e.g. replaceInPreviousCell[a->b]? A panel for this task? Or even a new button in the Ctrl+F panel ? – xzczd Mar 10 '17 at 6:02
• Your final suggestions are all very much suggestive! But your first one is definitely convincing. :) – Mirko Aveta Mar 10 '17 at 8:24
• Put a cursor before the cell -> find next -> replace and find next untill outside the cell. – Kuba Mar 10 '17 at 8:28
• @Kuba this is what I would like to avoid. My cell is enormous... – Mirko Aveta Mar 10 '17 at 8:29
• I see, do you want a general solution or do you want to replace specific symbol? Like myFunction and not e.g. whatever[expression, {could be there}] – Kuba Mar 10 '17 at 8:30
