Enable clicking on the Green circles in Eclipse to jump to code - eclipse

How can I enable clicking on this bubble (or perhaps the name) to instantly jump to the underlined place in code? By pressing f2 and clicking on a small box, the same effect can be achieved, but I remember being able to work far faster doing this on one of my old projects.

Hold Ctrl and hover over the method name. You can then choose to jump to the declaration or super implementation.

Access mouse over hover in VSCode

Is there a way to access the mouse over popup in VSCode via Keyboard and navigate in it?
I often use the mouse over to get the namespace of function or variable ...
So I want to place the cursor on "bar", popup the hover (Show Hover Ctrl+k Ctrl+i), focus it, mark some text (eg. namespace::functioname), copy and close the hover.
namespace foo{
void bar();
}
First problem, the hover doesn't get the focus and I don't know how to focus it. But there is another feature "Show defintion preview hover", which actually gets focused. So far so good. But I still cannot mark or copy text inside the hover via keyboard.
Show hover (not focused):
Show definition preview hover (focused):
But I still cannot mark or copy text inside the hover via keyboard.
That should change with VSCode 1.68 (May 2022):
Lock hovers to more easily mouse over them
Some custom hovers cannot be moused over and others are tricky to mouse over without hiding it because of other things in the way (eg. like a scroll bar).
Holding alt while a hover is active will now "lock" it, giving it a wider border and preventing moving the mouse outside of the hover widget or whatever triggered it from hiding it.
This is primarily an accessibility feature to make hovers play nice with screen magnifiers but it is also useful for copying text from certain hovers.
Note that this feature only applies outside of the editor because editor hovers can always be moused over unless specified otherwise via a setting.
This will be helpful for other views (debug, terminal, ...) where variables with their popup can appear as well.
In the editor, see microsoft/vscode issue 63296
ctrl+K ctrl+I to show the hover and focus it
ctrl+A to select all the hover content
ctrl+C to copy to clipboard
It does indeed work for me (on windows) for the first two steps, however ctrl+C does not copy the text selected with ctrl+A.
It seems like there are two different selections possible in the hover:
ctrl+Aselects everything with a dark blue.
When selecting some text in the hover with the mouse (i.e. press the left mouse button while near/over a char, move mouse, release left mouse button) the selected text is shown in a lighter and brighter blue.
The two selections can coexist.
ctrl+C always copies the text selected with the mouse, or nothing if there's no such selection, no matter whether a ctrl+A selection also has been done.
If there's only a ctrl+A selection, ctrl+C doesn't copy anything.
The two selections can be selected in any order. The order doesn't change the behavior.
Think I found out what you were after.
The shortcut is: Ctrl+K Ctrl+I

In Eclipse, a way to see code errors without moving the mouse?

I've programmed in Emacs for a while, and I'm starting to learn Java in Eclipse. I prefer not to have to take my hands off the keyboard in order to see errors that Eclipse marks in the code... so I'd rather not hover over them, (plus the red X on the left margin is annoyingly small and hard to target for a hover)... is there a way to get them to pop up simply by moving the cursor to that point?
The "Show Tooltip Description" command usually has the keybinding of F2. You can change it on the Keys preference page if you like.

How to navigate up/down using keyboard home keys in Eclipse's suggestions pop up window?

When Eclipse shows a popup for code completion, how do you change the highlighted option using the keyboard home keys? Currently, if the thing I want is third or fourth on the list of suggestions, I have to use the mouse to select it, or use the arrow keys. Is there a way to use the keyboard home keys/ shortcuts with ctrl/alt to do this?
Arrow keys always work for me. Can you be little more specific as to what perspective, editor, etc?
I get a code completion popup when I press Ctrl + 1 in the Java editor. From then on, I can use the arrow keys to navigate.
I'm assuming you want to select from the code completion menu by X for up and Y for down. Go to Preferences > Keys and bind the commands Line Up and Line Down to X and Y, respectively. Make sure that in the When drop-down you select In Windows.
Note that after the settings are applied, X (Y) also makes the cursor go one line up (down) in the source editor. Personally, I use X = Ctrl+P and Y = Ctrl+N which means I can navigate lines and select entries from the code completion menu without lifting my hands off the keyboard.
Unfortunately, these bindings don't work with other pop-up lists in Eclipse, e.g. quick outline (Ctrl+O) or quick access (Ctrl+3). I'd love to find out how to bind these too.

How can I go to the next Eclipse marker (e.g. build error) using the keyboard?

Suppose I make a method signature change that breaks several callers, and I want to review the call sites manually to update them.
Once I change the signature, my "Problems" view shows, say, a dozen errors.
What keys can I hit to navigate through them while leaving the keyboard focus in the editor for fast fixups?
(It's been a while, but I think the Visual Studio equivalent is F8.)
Note that this question does not duplicate Eclipse: How to go to a error using only the keyboard (keyboard-shortcut)?, as that one seeks to navigate only between markers in the current file. In this case, I want to go to the next error regardless of which file it's in.
("Marker" is the general Eclipse term for errors, warnings, etc.)
The best I've come up with so far is Ctrl + F7 to flip to the Problems view, then ↓ to pick the topmost error, then Enter to go to it (which returns focus to the editor).
Here's a way to move to the next error, regardless of editor, in one keystroke. It's not perfect, but it works until it's fixed in Eclipse.
Open a "Markers" view. Click the down arrow at the top right, and choose "Configure Contents". Uncheck the show all box, and create the view to show only the problems you want to see. You'll probably want to deselect "warnings" and "errors" as well. Save it.
Click the same "Markers" down arrow, and choose "Group By". Select "None". This is important because you don't want the parent tree level nodes to show, otherwise some of your "next" actions will take you to those, which don't represent an error.
In Eclipse -> preferences -> keys, search for "Markers". If there is not a keystroke bound to the Markers view, create one. I use Ctrl + Shift + M
Get a keyboard hotkey tool like AutoHotKey (for PC's) or iKey for the Mac. I'm using iKey, but there are plenty of other Mac tools you can use. In your hotkey tool, define an action for the keystroke you want to use for "next error". I chose the standard CMD + .
For that keystroke/action in your hotkey tool, generate 3 keystrokes in the following order:
Ctrl + Shift + M
Down arrow
Enter
Of course, you'll want to change the first one to whatever you picked for yours. You'll probably want to restrict that action to be executed only when Eclipse is the current application.
Save that, create some compile errors, and test it.
Try Ctrl + 3 for Quick access popup window.
If the "Markers view" is not already visible, then type in "markers", in the searchbox on the popup window. Once you have selected it, it should stay available, when you press Ctrl + 3 the next time around.
I just had the same problem, after refactoring some parts of code. I had a lot of errors in different files and i had to go through all of those.
I used the following solution:
Mark all (relevant) entries in the Problems view.
To do this switch to the Problems view using Ctrl+F7 and select the entries with Shift+↓/↑
You can also select all entries using Ctrl+A
Open the marked errors by pressing ↵.
Every file containing at least one marked error will be opened.
The cursor will automatically select one error/file, as if you open only this specific entry
Fix the errors in the opened file.
Here you can use Ctrl+. to navigate to next error inside this file
Close the file using Ctrl+W when your done.
Eclipse will automatically focus the next file and you can go back to step 3
In my case this solution was much faster then switching to the Problems view each time.
There's an Eclipse bug entered for this that has an attachment that looks like it does what you want.
You could use AutoHotkey:
save the mouse position, send a mouse event to click on the arrow in CDT console and then return the mouse back to it's original location. Record the mouse coords with window spy or use autohotkey's search by image function (first capture the images of two arrows with printscreen into bitmaps).

Faster way (keyboard shortcuts?) to use quick fixes in Eclipse?

I often use the Eclipse feature (Galileo) of suggested error corrections to automatically create code stubs or to refactor things. For example, I would write a method that calls other methods which don't exist yet, then move the mouse over the error message and click on "create method". Or, change this to the class name and choose "add static modifier" from the quick fixes.
I think this is very convenient because it lets me stay in one place in my code and sort of "remotely" wire up what's not currently visible on my screen. What I think is annoying though, is that I have to leave the keyboard, hover my mouse over the error symbol, wait for the tooltip to pop up, and click on the option (doing that, I sometimes move the mouse a little over the edge and the tooltip goes away again - very annoying).
Am I missing a faster method here? I can't seem to find a keyboard shortcut, but then I have overlooked stuff from the huge preference dialog before.
Ctrl+1 : Quick Fix.
(Cmd+1 on Mac)
Just put your cursor on the part you suspect you can perform an action (correction, refactoring, ...) and hit the Quick Fix shortcut. The same popup will be displayed, and you can select the right option with the up and down keys.
That, combined with Ctrl+3 (Quick Access) gives you most of eclipse features at your fingertips ;)

As an additional tip, a specific type of quick fix I use all the time has a dedicated shortcut:
Alt+Shift+J: Add Javadoc comment stub for current method.
After using ctrl+1 like mentioned in the top answer, press ctrl + enter to apply the selected fix all to problems of the same category.
In general, keyboard shortcuts in IDEs (and code tools in general) are coming from a user principle that holds that the more your hands/fingers can remain poised over the keyboard (as in the f-j centered "touch typist" position), the more productive you can become. This is probably why the use of the number keypad is not encouraged, or other keys, less common to the most basic layout keyboard, are not used. Many hold that useful keyboard shortcuts should be easily reachable from this position.
One thing I will say about eclipse keyboard shortcuts is that if you use a popular Windows presentation utility called Zoom-it, you need to turn that off when using eclipse. There are several show-stopper conflicts between the two, such as Ctrl-1 and Ctrl-3.
