Shortcut Keys (1)


In our previous article on shortcuts, we covered the Editing section, but today we’ve managed the rest (●’◡’●).

Are you ready

Let’s just get started!


Refactor

I usually use a lot of this one (●’◡’●) because it’s really handy.

1. Extract local variables

WIN : Ctrl + Alt + V

Mac :

This shortcut is really convenient, many times we can save ourselves to declare variables.

And you can see, just with your little finger, amazing things happen


2. Extract constants

WIN: Ctrl + Alt + C

MAC:

This shortcut can be used when you want to extract constants instead of local variables.

Use effect


3. Extraction method

WIN: Ctrl + Alt + M

Mac:

This shortcut can encapsulate the selected code block directly into a method, which is also used very often when expanding.

Results show

Ovo, which is mostly about functions, is usually a little bit more code extracted into methods


4. Extract method parameters and fields

These two are used relatively sparingly

Extraction method parameters

Win: Ctrl + Alt + P

Mac:

Extraction of field

Win: Ctrl + Alt + F

Mac:


5. Rename (files, variables, methods, etc.)

WIN: Shift + F6

Mac:

Results show

So let’s just show the change variable here, and you can see, you can change OwO here, you can change OwO here

The same goes for other things.


6. Modify the method signature

WIN: Shift + F6

Mac:

This shortcut allows you to modify the method signature directly, which is sometimes useful.

Click method, then press the shortcut key, will pop up the modify box, the same is a modify, modify everywhere.

These are the ones that are used a lot for refactoring. Ovo, let’s move on


Navication

Navigation helps us quickly switch to where we want to go


1. Open the sidebar

Win : Alt + F1

Mac :

This shortcut is quite frequent and can reduce the number of times we use the mouse.

Results show

After pressing Alt F1, use the up and down keys to quickly switch.

To turn it off, press Shift+Ese or press Alt F1 a few more times


2. Quickly cut the Tab

Win: Alt + Right/Left

Mac:

Used to show

← is the previous one

→ is the next one


3. Back/forward

Win: Ctrl+Alt + Left/Right

Mac:

This is very similar to cutting the Tab, but mostly it’s back to the last edit or forward to the next edit.


4. Display the recently accessed Tab

Win: Ctrl + E

Mac:

This shortcut will give you quick access to Tab

Results show

After pressing Ctrl+E, we can directly type the name of the Tab we want to go to, and then press Enter


5. Display the file structure

Win: Ctrl + F12

Mac:

When we have a complex file structure, using this shortcut can help us see the file structure clearly

Search

The search section can help us quickly search the target keywords and so on


1. Search the keywords of the current Tab

WIN: Ctrl + F

Mac:

I’m sure you’re familiar with this shortcut, so I won’t tell you more about it here.


2. Replace the keywords of the current Tab

Win: Ctrl + R

Mac:

I’m sure you’re familiar with this shortcut, so I won’t tell you more about it here.


3. Find where and how often (methods, variables, etc.) are used

WIN: Alt + F7

Mac:

This shortcut is useful when we need to know where a variable or method is used

4. Search for files

Win: Ctrl + Shift + N

This shortcut can help us to find related files, such as when looking for source code, very convenient.
