I want to achieve the same action that Alt+up/down does, to left and right movement of a code selection.
for example,
if I have this code an[] if I select n and press a shortcut to move it right it should become a[n]. Is there any shortcut for this? If not, is there a way to custom define this?
I use Eclipse Luna.
There is no command to do that. if you look at the General > Keys in preferences, you can see that there are only commands for Move Lines Up and Move Lines Down.
So you have to keep going with drag & drop.

When I compare two versions of a source file (for example, from egit) in the Eclipse IDE, the Compare View is appeared. It has two panes containing two versions of a text and I can use keyboard to move cursor through the text on one of this panes (or even edit the text in it). Additionally, I can use special shortcuts to go to the next/previous difference and/or apply current change from/to the opposite pane. But, I didn't find a way to move the input focus to other pane.
Actually, I would like be able to do this in one case. Let's say, I compare two revisions of a source and I need to apply some changes while others are unneeded. To achieve this, I walk through changes using the Ctrl + , or . shortcuts and apply needed changes using, for example, the Ctrl + Shift + ,. It looks like all is OK, but if I reach a change which has no any text in the current pane, the applying shortcut does not work. For example, the cursor is on the left pane. I went to the next difference and this difference is concluded in that the text was, for example, added in this line. So, the Compare View will show this added text on the right pane, will highlight it with the special rectangle while this rectangle on the left pane will have zero height and the cursor will be placed under this zero-sized rectangle. I.e., outside of it. So, I think, exactly this thing causes that the current change applying does not work. When I click on the opposite pane, inside of this change and then use the change applying shortcut, it works fine. So, I would like to switch to other plane via shortcut, not using mouse.
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.
I want to use a shortcut to move the cursor to the next line or previous line.
I can't find this Command in Preferences->General->Keys.
Are there any plugins that can do this? Or do I have to develop my own plugin to for that? If I have to develop it, which extension point should I use?
If I am understanding your question correctly then you should be able to set the Eclipse Key Mappings for Up Arrow and Down Arrow keys.
Search for "Line Up" and you will see
Line Up
Scroll Line Up
Select Line Up
These should already be mapped to Up/Down Arrow and Shift Up/Down Arrow, but if not (eclipse does mess up keyboard mappings from time to time) you can add them back or set them the way you want.
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.
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).
