Eclipse - How to disable "direction" on find/replace dialog - eclipse

In eclipse, when using the CTRL+F dialog, it is a bit annoying to search for some word in a file and having to select the direction you want to search (forward or backward) or having to put the cursor focus at the top of the file to search forward.
Is it possible to disable this direction option and search for words just like Chrome does? (when searching in Chrome, if you reach the last coincidence and press next again, it will go back to the first one immediately).

In the Find/Replace dialog in the section Options there is the checkbox Wrap search for that.
The Wrap search option of the Find/Replace dialog is also applied to the Find Next (Ctrl+K) command.
Alternatively, you can use Incremental Find (Ctrl+J) which is a Find without a dialog: in the Incremental Find mode the entered search string is displayed in the status bar and by hitting Ctrl+J again you go to the next match. On the last match you have to hit Ctrl+J twice to go to the first match.

VSCode how to automatically insert Intellisense suggestions without having to press Enter?

Default VS Code Intellisense behaviour
User is presented with a menu of suggestions
User then has to press the Up or Down arrow keys to navigate through the menu
Finally user has to confirm with Enter to insert the suggestion and close the dialog
What I would like instead
Don't need to press Enter
Suggestions are automatically inserted (and cycled through) by pressing Up/Down
Pressing any other keys will close the dialog and resume typing
To be clear, I want to replicate the default behaviour of YouCompleteMe:
When you type, a completion menu pops up. If you like the completions, you use the <Tab> key (by default, can be changed to <Enter> or <Down> arrow or whatever) to select a completion string you want. The very act of "tabbing through" the list to select the item you want inserts the candidate string. When you tab to a different candidate, the editor code is replaced with the new candidate. There is no accept key because by the point where you have the candidate you want selected in the menu the candidate has already been inserted in the editor. There is nothing to "accept". You just keep typing, the candidate has already been inserted.
Is such behaviour possible with Visual Studio Code, either by default or through a plugin?
The editor.tabCompletion option is the closest thing currently available:
By default, tab completion is disabled. Use the editor.tabCompletion setting to enable it. These values exist:
off - (default) Tab completion is disabled.
on - Tab completion is enabled for all suggestions and repeated invocations insert the next best suggestion.
onlySnippets - Tab completion only inserts static snippets which prefix match the current line prefix.
(Emphasis mine)
... except that the first Tab press hides the suggestion window.
I did some digging about editor.tabCompletion, and I found that closing the suggestion window is part of the tab completion's option original design, and that while other users have asked about an option not to close the suggestion window or specifically YouCompleteMe-style behaviour, that this is currently not supported.
"editor.acceptSuggestionOnEnter": "off",
To disable Enter to accept suggestion.

Search box in Eclipse

When I hit Ctrl+F in Eclipse, it would bring up a search-box asking for the term, etc.
That's annoying because if I'm on a small monitor, the pop-up would cover most of the text.
Does Eclipse have a search-bar at the bottom (or top) of the editor like Netbeans does?
(In Netbeans, when you hit Ctrl+F, a very small search-bar would appear at the bottom/top of the editor).
You can use Increment find for this. Press Ctrl+J.
Then observe in the status bar THAT incremental find is activated. Then you can go on typing your search term the first occurrence of word will be highlighted in editor if found else you will get <search term> is not found error(in red colour) in status bar.
Refer the image below
Note:
You can cycle through forward the next occurrences by pressing Ctrl+K and backward by pressing Ctrl+Shift+K
If the shortcut key for incremental find is NOT working then check the short cut keys for Increment Find and Reverse incremental Find commands in
Windows->Preferences->Keys section

remove search highlighting via keyboard shortcut in Eclipse

After doing a Java or File search in Eclipse, the (purple) highlighting of matches in files persists indefinitely, distracting me from whatever task I try to accomplish after I complete my search.
I know that I can open the Search view (by pressing Alt+Shift+Q,S, or by clicking its icon) and then click the "Remove All Matches" button that looks like an advertisement for Dos Equis, but I get tired of all this view-activating and clicking.
I want to clear search results in Eclipse using just the keyboard. Is there a way to do this?
Press Ctrl+F7. Keep on Pressing F7 when reach search view. Release Ctrl Key.
Close search view(in fact any view) as explained here
Once search view is removed from the current perspective search highlight will be removed automatically. If you want to see it again then open search view.

How to enable "live search" in eclipse?

In Komodo Edit, an input field is available in the toolbar. When I type text in it, it highlights matching search results. Is there something like this in Eclipse, either directly or via a plugin?
As TK Gospodinov has already mentioned, there is an Incremental option in Find/Replace (Ctrl+F) dialog.
There is also a special key binding for Incremental search in Eclipse (and personally I use it more frequently). From Eclipse Tips and Tricks:
Use Edit > Incremental Find Next (Ctrl+J) or Edit > Incremental Find Previous (Ctrl+Shift+J) to enter the incremental find mode, and start typing the string to match. Matches are found incrementally as you type. The search string is shown in the status line. Press Ctrl+J or Ctrl+Shift+J to go to the next or previous match. Press Enter or Esc to exit incremental find mode.
If you'd like to have search functionality in a toolbar, you may be interested in the eclipse-glance plugin, which allows you to use the incremental search function in a toolbar by pressing Ctrl + Alt + F while in any text area.
This feature is already available in eclipse. No need to install any plug-in.
Press Ctrl+F, and the Find pop up appears.
Now check the incremental checkbox, and then your texts will be found as you type. No need to hit return.
OR
Use Ctrl+J and you can activate the live search, just that there wont be any UI visible, but you can see the status in eclipse status bar at the bottom.
Press Ctrl+J, start typing the text you want to search for. Press esc to go back to edit mode
The closest thing to the functionality you are asking about is the 'incremental search' mode, which is triggered by checking the 'Incremental' checkbox in the Options group on the Find/Replace dialog in Eclipse (Ctrl+F from the code editor). This will make it start highlighting matches as you type, and if they are keywords, Eclipse will highlight other occurrences (references) in the code editor. Matches inside strings or Javadoc will not be highlighted, however, unless it happens to be the first match after your cursor's position inside the editor.
One similar thing (not the same) is just enabling "mark occurences", then selecting function name, variable etc.

How to cancel search highlight in Eclipse

When I search something in Eclipse, the search items stay highlighted for some time. How do I remove this after I have found what I was looking for?
Remove your matches in the search view, that will remove the highlighting. I.e., click the button with the two X's in the search view.
If you cannot see that view, navigate to window -> show view -> Search
AFIAK, the search result view has a toolbar button to clear the search results. This removes the highlighting in the editor.
An alternative way is to run a search that will yield no results. For example file search, containing text - leave this field empty, files - some stupid extension like ".qwe".
For people concerned that https://stackoverflow.com/a/3545215/6012102 removes search results from history.
Select the search from history, press "Run the current search again" (2 rotating arrows icon). This will run the search and you will get all the results back (this brings back the text highlight as well unfortunately).
Disable Preferences->General->Text Editors->Annotations->Search Results->Text as.
For a single instance, delete the line and undo it: Ctrl+DCtrl+Z. This is faster than the other answers, and worked when they failed (for some buggy JSP I had).
