Here’s a list of several shortcuts with some explanations of why they are useful. I’ll try to list them in order of usefulness. There are very few navigation shortcuts in here, and I will hopefully make a new post that outlines all the navigation shortcuts that I’m not currently using.
| Shortcut | Function |
|---|---|
| Shift + F6 | Rename Variable |
| Ctrl + P | List function parameters |
| Ctrl + Space | Trigger autocomplete manually |
These are the basic shortcuts everyone should really be using. Rename variable and alt + enter are probably the most useful. List function parameters is a recent one I’ve learned that is handy a lot. Autocomplete allows for grabbing methods without having to look at the function itself etc.
| Shortcut | Function |
|---|---|
| Alt + Up/Down Arrows | Move line Up/Down |
| Alt + J | Grab next occurance of whatever is highlighted |
| Ctrl + Left/Right Arrows | Skip to next word |
This set lets you move things around. Alt + J and combined with Ctrl + arrows lets you skip between things in multiple lines and apply whatever is needed - good for mass editing. Moving lines up and down is slightly faster than cut/paste and looks a little bit fancier.
| Shortcut | Function |
|---|---|
| Alt + Enter | Fix some kind of warning/error, Other functionality |
| Ctrl + Alt + M | Extract Method |
| Ctrl + Alt + N | Inline Variable |
| Ctrl + Alt + V | Extract Variable |
| Ctrl + Alt + P | Extract Parameter |
| Ctrl + Alt + F | Extract Field |
Most of the refactoring shortcuts are ctrl + alt + some command. If you want to learn one shortcut only, remember the the first one. That shortcut (alt + enter) will allow for a lot of functionality that is built-in to the editor.
The general search window is very useful and can be displayed by using shift + shift. There are shortcuts to go to each individual tab as detailed below.
| Shortcut | Function |
|---|---|
| Double Click Shift | Search Window |
| Ctrl + N | Go to Class |
| Ctrl + Shift + N | Go To Files |
| Ctrl + Alt + Shift + N | Go To Symbols |
Moving around in the editor, these shortcuts are used frequently. The goto error and previous error is especially useful to find compile errors. Its also possible to jump between methods.
| Shortcut | Function |
|---|---|
| Ctrl + B | Go to Declarations or Usages |
| Alt + Up | Previous Method |
| Alt + Down | Next Method |
| F2 | Go to Next Error |
| Shift + F2 | Go To Previous Error |
I use goto declaration or usage frequently, and need to start trying some of the other shortcuts in here more frequently.
| Shortcut | Function |
|---|---|
| Alt + Home | Jump to Navigation Bar |
| Ctrl + B | Go to Declaration or Usages |
| Ctrl + Alt + B | Go to Implementations |
| Ctrl + Shift + B | Go To Type Declaration |
| Ctrl + Shift + T | Go To Test |
| Ctrl + F12 | File Structure |
| Ctrl + Alt + F12 | File Path |
