Remember that there's a lot more to programming than just throwing down code in an IDE. A good senior programmer is going to have a toolbox full of programs that they're very comfortable with and can leverage to great effect. At the very least, this is probably going to include a text editor, a diff/merge tool, one or more database clients, a source code control interface, maybe a specialized find-in-files tool, and others.
Everyone's got their own combination of tools they prefer to use. I'd suggest observing which ones your senior developers have elected. Pick their brains and find out why. Not everyone's given it a lot of thought, but you're likely to find some of your coworkers have spent a lot of time considering their environment and can tell you exactly why they use gvim for their editing when most of the team is on Notepad++, or why they think WinMerge is the perfect tool for deploying hot of the press code to the test server. People inherently like talking about themselves, and you can learn a ton getting an expert to describe his environment.
From there, spend some time practicing with those programs yourself. Learn how they work and what they can be used for. Spend some time dabbling with the advanced features. You certainly won't become an expert in everything on day one (or year one), but at least become familiar with what each tool can do, so when you encounter a situation where it would help, you recognize it and know where to start.
From there, never stop learning, and never stop experimenting. Always be on the lookout for better tools, or better ways to use the ones you're already familiar with. Over time, you'll pick up programs that work well for you and become permanent members of your toolbox, and you'll have some highly recommended to you that just don't fit with the way you think. That's great. Keep at it, and in a couple decades, you'll have you're own hand chosen set of tools that you're very effective with, and you'll be the one being asked by the eager young developer trying to get started.
