How do you search notes on a macbook?

Question

So, I finally bought a Mac after realizing that they are far more efficient than their competitor. I am learning how to use it, but perhaps I am very stuck in my old Windows habits. I used to keep a lot of usernames and passwords in a simple text file on my PC and everytime I went to a forum or website that asked me to log in, I would simply use CTL+F to find the web address, and then be able to see what email/username/password I used for that particular site.
On getting my Mac, I transferred this file to the Mac, so that I can continue to use the text file, but now I can't seem to find a way of searching within the text to find a particular string.
Is it possible? Please can someone tell me what the key combination is. I have looked but cannot find it. Thank you, in anticipation.

Answer 1

Thank you Carolyn. I tried Spotlight and sure enough, it finds the files that contain the text I searched for, but it didn't seem to highlight the text within the file. For example, there is a soccer player called 'something Laudrup' and I can't remember his first name. I know it's somewhere in the text below and I'd like to find the line of text that it's in.
Is there a way to do this? Before I jsut used CTL+F and typed in 'Laudrup' and it would take me straight to the first instance in the text of 'Laudrup' and also offer me a next. Pretty much the same as finding text on a website, where of course, cmd+f works
Here's the sample text..
It was certainly an evening to remember for England Under-21 international Shelvey, who left Anfield for the south Wales club in the summer. The £5m signing put the Swans ahead when he left new Reds defender Mamadou Sakho flat-footed to calmly stroke a left-foot effort past goalkeeper Simon Mignolet. Liverpool had not previously conceded in the Premier League and they were gifted a way back into the game little over 100 seconds later by Shelvey. His careless pass back towards goalkeeper Michel Vorm was seized upon by Sturridge, who netted his fourth top-flight goal of the season with a clinical finish. Sharp Sturridge Daniel Sturridge is the first player to score in each of Liverpool's first four games of a Premier League season. The Reds dominated the opening half hour as the vibrant trio of Moses, Philippe Coutinho and Sturridge pulled apart the Swansea defence with pace and precision. And they should have doubled their advantage when Moses and Sturridge combined. On-loan Chelsea winger Moses surged past two defenders near the left corner flag and dinked in a perfectly weighted cross towards an unmarked Sturridge. The England striker seemed certain to score but his header was directed too close to Vorm, who made a magnificent save. Shortly before half-time, they did take a deserved lead. Shelvey sloppily handed possession to Moses, who drove at the backpedalling Swansea defence before accurately shooting into the bottom corner from the edge of the penalty area. Victory would have given Liverpool their best start to a season since 1990-91 and for the opening hour they seemed firmly on course to achieve that. But Coutinho's departure early in the second half with a shoulder injury following a robust challenge from Swans skipper Ashley Williams disrupted their fluency. Miserly Liverpool Jonjo Shelvey's goal was the first Liverpool had conceded in the Premier League in 419 minutes of play Swansea, playing the first of seven games in 21 days, had not created any clear-cut second-half chances before Michu's leveller, but they had been encouraged to press forward by Liverpool's willingness to sit back on their lead. They were rewarded when Shelvey flicked a right-wing cross into the path of Michu, who swept a first-time shot beyond Mignolet. The leveller switched the momentum of the match firmly in Swansea's favour and, as the encounter moved into the closing stages, Michael Laudrup's men looked the likeliest to grab a dramatic winner. Shelvey sent a low free-kick fizzing into the arms of Mignolet, before substitute Jonathan de Guzman twice went close. Swansea manager Michael Laudrup: "We had to perform better in the second half and the boys did a good job. "We got the equaliser, we could have won the game but I'm pleased with the result after all." Liverpool manager Brendan Rodgers: "I thought for the first 65 minutes we were very good. We showed incredible character to get back level so soon after they scored. "I was disappointed with their second goal and then the momentum changed for the last 25 minutes and we had to show character and resilience. "But we showed tonight our game is getting better and we have the character to get a lot of results."
