I have a PDFView in an app. It allows you to highlight certain text. When you click on a highlight, the built in menu appears:
In the Preview.app, when you click one of those colors (or the remove highlight) menu item, it does what you expect (changes colors; removes the highlight). In my PDFView, this context menu does pop up, but does not change colors or remove highlights. Add note and others (e.g., single page, zoom in, etc.) seem to work out of the box. How do I implement an event handler for these default contextual menu items?

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

I find the explorer tree to be unintuitive. Opening a file on single click was annoying, so I set "workbench.list.openMode": "doubleClick". Now I have to click twice on the expand/collapse triangle just to make the tree expand or collapse (in code outline view, gitlens, and other views).
Shouldn't single click on the twisty open/close?
Why can't you type letters to navigate in lists/trees?
Why is the item you clicked on one color, but the item you navigate to with arrow keys another?
What is the point of the other highlight, as the context menu only seems to apply to the highlight with less contrast?
How do I open the selected item with the keyboard?
What is happening in the explorer when you press ESC? Seems like focus moves to the tree itself, but what does that achieve?
Shouldn't single click on the twisty open/close?
I've seen an open issue about that
Why can't you type letters to navigate in lists/trees?
That issue exists too
Why is the item you clicked on one color, but the item you navigate to with arrow keys another?
IDK. Usually, after you click that file is open in editor. (Selected list item - active editor(easier to spot?); Focused list item - where the focus is)
What is the point of the other highlight, as the context menu only seems to apply to the highlight with less contrast?
You can change the colors if you want to.
How do I open the selected item with the keyboard?
Enter? I assigned arrow right→ though.
What is happening in the explorer when you press ESC? Seems like focus moves to the tree itself, but what does that achieve?
What did you expect it to do?
I accidentally removed search icon in Activity Bar and don't know how to add it there again. If I click on Activity Bar, I don't see this option any more.
Update: v1.44 you can now simply drag many of the views, including "Search" from the sidebar to the panel and back. See https://code.visualstudio.com/updates/v1_44#_increased-view-placement-flexibility and https://stackoverflow.com/a/55981465/836330
Update: v1.42 added a context menu option
Move to Panel/Move to Sidebar
to certain typically sidebar views like Search, Outline and custom views. So you wouldn't have to use a setting to move the Search view back to the sidebar. Here is a demo:
Also notice that you no longer right-click in the empty space below the search inputs in the sidebar but on/near the Search header itself to bring up the toggle option.
As part of the v1.42 release the search.location setting mentioned below will be deprecated.
Your setting should migrate automatically, but you will need to use
the new generalized method to move the Search view going forward. You
do not need to enable the experimental preview setting above in order
to move the Search view with the new context menu entry.
So I don't think there is a setting anymore, you just right-click on the header text "Search" whether it is in the Panel or active in the Sidebar to move it. See the demo below.
Right-click on the "Search" header if you have it in the sidebar to "Move to Panel".
If Search is in the panel, right-click on the word Search to "Move to Sidebar".
To enable moving the Output view at this point, you need to enable workbench.view.experimental.allowMovingToNewContainer.
There is a new unbound command workbench.view.search.moveView which you can use to toggle the search position between the panel and sidebar. But note that in my testing it only works a couple of times because it focuses the panel when you move search to the sidebar - I'll file a bug.
Previous Answer::
You may have modified the setting:
"search.location": "sidebar",
which is the default to the alternative
"search.location": "panel",
which would put the search widget into the terminal panel as another tab.
As of vscode v1.35 or so, you can now right-click in the empty space below the search view (i.e., in the sidebar under the open search inputs) and you will get an option to Toggle Search View Position.
This context menu switch of the search view is persistent. It will automatically add this setting to your settings.json:
"search.location": "panel",
The only way at present (but see edit just below) to move the icon back to the activity bar (and thus the search across files functionality to the sidebar) is to change that setting to the sidebar option. Or look for this setting in the settings editor:
Search: Location
Controls whether the search will be shown as a view
in the sidebar or as a panel in the panel area for more horizontal
space.
EDIT: More recently, vscode added the abilty to right-click in the search area when it is in the panel to toggle it back to the sidebar.
In windows
file--> preferences-->settings
In mac

I open a context menu programmatically. Now additionally I would like to highlight the first menu entry.
This highlighting happens when I move with the mouse over the context menu or press the arrow keys on the keyboard. I am interested how I can trigger this programmatically.
I know the API of MenuItem does not offer this feature out of the box. So I tried to fire some MouseEvents of the type MouseOver and MouseHover, but without any success.
Has anybody an idea how to implement this feature?
I am not sure if you can change menuitem highlight colors, I haven't seen any previous example before. Look at this though: Change eclipse menuitem color
If you want to simulate what the user does and if you happen to know the location of the menu item, you can use Display#setCursorLocation() to position the mouse pointer over the menu item.
Note however, that if and how a menu item is highlighted is platform specific.
You should not use this method other than for demonstration of test purposes. If your application needs to highlight or preselect an entry in a list of choices,
you should probably use another widget. If you more describe your use case, we may be able to find a suitable widget.
I'm using the Kepler CDT release (4.3.1) of Eclipse. When I click on anything in the Outline view, the corresponding editor view is reduced to showing just that item. If I click on a variable, I get a single line with just that variable. The Edit->Expand Selection options are all dimmed out. Hitting Shift-Alt-Up Arrow just moves me up to the previous item in the outline view. If I change editor tabs and come back then the Expand Selection options enable and I can manually hit Shift-Alt-Up Arrow a number of times to make the entire file visible again but clicking on anything in the outline view again will just reduce the view. Is there some new setting in Kepler that will make outline stop doing this?
Turns out the feature for Show Source of Selected Element Only was turned on. In Kepler the toolbar button for this is not visible. Even searching under quick access doesn't turn it up so it's somewhat of a puzzle how it could have been turned on. I actually thought maybe it had been removed from Kepler.
In the Customize Perspective dialog under the Tool Bar Visibility tab. In the Tool Bar Structure section I opened the area for Editor Presentation. I noticed there was actually a check next to the box for Show Source of Selected Element Only. However, it wasn't visible in the toolbar (a bug I've seen before in Eclipse) so I unchecked it and checked it. Then I exited the dialog. Now the button showed up on the toolbar. I then toggled the feature on and then off. Now clicking in the outline view works correctly.just moves to the correct spot.
