I am still relatively new to Linux Mint.
Like many people who move to a new operating system, I am slowly discovering all the little things that are hidden in plain sight.
Sometimes I search for a feature because I need it.
And sometimes...
I accidentally press a keyboard shortcut and discover something I didn't even know I wanted. 😄
That is exactly what happened to me recently.
The accidental discovery
I was working with my files in Linux Mint's file manager, Nemo.
I don't even remember what I was doing. I probably pressed some random combination of keys while navigating around.
And suddenly...
My file manager split into two panes.
I was like:
"Wait... what just happened?"
Instead of seeing one folder, I now had something like this:
And my first reaction was:
"Oh... this is actually really useful!"
What is this feature?
It turns out that Nemo, the default file manager in Linux Mint's Cinnamon desktop, has something called the Extra Pane, or Dual-Pane view.
The idea is beautifully simple:
Instead of opening two separate file manager windows and constantly switching between them, you can have two locations visible inside the same window.
The current Nemo shortcuts list calls this "Toggle extra pane", and the keyboard shortcut is F3.
So:
Press F3 → two panes
Press F3 again → back to one pane
That's it.
And somehow, such a small feature makes file management feel completely different.
Why is a second pane so useful?
Think about the number of times you do something like this:
- Open a folder.
- Find some files.
- Open another folder.
- Copy something.
- Go back.
- Find the first folder again.
- Paste.
- Repeat.
Nothing complicated.
But you are constantly navigating back and forth.
With two panes, you can simply keep the source folder on one side and the destination folder on the other.
For example:
Now you can select your photos and move or copy them between the two locations.
This is particularly useful when working with:
- Photos from a camera
- Video files
- Project folders
- External drives
- Downloads
- Large collections of documents
- Organizing images
It feels a little like having two file managers
This was probably the biggest thing I liked about it.
Normally, if I want to work with two locations, I might open:
Window 1 → Photos
Window 2 → Edited Photos
Then I have to resize the windows and arrange them on the desktop.
With the dual-pane view, everything is already inside one window:
┌───────────────────────────────────────────────────┐
│ Nemo │
├────────────────────────┬──────────────────────────┤
│ │ │
│ Photos │ Edited Photos │
│ │ │
│ IMG_001 │ IMG_010 │
│ IMG_002 │ IMG_011 │
│ IMG_003 │ IMG_012 │
│ │ │
└────────────────────────┴──────────────────────────┘
It feels much more intentional.
And once you start using it, the single-pane layout can suddenly feel a little strange.
The keyboard shortcut I accidentally discovered
The shortcut is:
F3
That's all.
Nemo's current shortcut definitions list F3 as the shortcut for toggling the extra pane.
There are a couple of other useful shortcuts related to the two-pane mode as well:
| Shortcut | What it does |
|---|---|
| F3 | Show/hide the extra pane |
| F6 | Move focus between the two panes |
| Alt + S | Go to the other pane's location |
You can also make it the default
Here's another thing I discovered.
If you decide that you actually prefer the dual-pane layout, you don't have to press F3 every time.
Nemo has a setting called:
Always start with dual-pane view
You can find it under:
Edit → Preferences → Behavior
and enable the option for starting with the dual-pane view.
This means new Nemo windows can open with both panes already available.
Why I like this as a Linux beginner
One thing I am slowly learning about Linux is that some of its best features aren't necessarily the flashy ones.
There are no fancy animations here.
No AI.
No huge productivity dashboard.
It's just:
"What if we put two folders next to each other?"
And honestly...
that's pretty great.
As a beginner, I also like discovering features this way.
I didn't read a giant Linux manual.
I didn't spend an hour configuring something.
I accidentally pressed a key.
And suddenly I discovered a feature that makes sense for the way I work.
That's one of the fun parts of learning a new operating system.
A small feature, but a big productivity improvement
I think this is something worth remembering when moving to Linux.
Sometimes we compare operating systems based on huge features:
- Which one is faster?
- Which one looks better?
- Which one has more applications?
- Which one has better hardware support?
But after actually using an operating system for a while, it's often the small things that start making a difference.
A keyboard shortcut.
A better workflow.
A tiny setting hidden inside Preferences.
A tool that saves you a few clicks every day.
Those little improvements add up.
And for me, Nemo's dual-pane view is one of those discoveries.
Try it yourself
If you're using Linux Mint and haven't tried this yet, open Nemo and press:
F3
You should see the second pane appear.
Then try something simple:
Left pane → Downloads
Right pane → Documents
Now move between the two panes and try copying a file.
You might find yourself thinking the same thing I did:
"Why didn't I know about this earlier?"
Final thoughts from a Linux beginner
I'm still learning Linux Mint.
I'm sure there are probably hundreds of other little features hiding in menus and keyboard shortcuts that I haven't discovered yet.
And that's actually what makes it fun.
Every now and then, I press the wrong key...
...and Linux teaches me something new. 😄
Today's accidental discovery: F3 → Dual-Pane Nemo.
Definitely keeping this one.
