say, I want to search for a particular text withing a function block.
The present way, that i am implementing is selecting the block of code from within the function brackets with vi{ and then copying it and pasting it to a new file. After that I am searching for the text within the new file with /<search-text>
I want to know, if there is a short cut to this?
vi{
:'<,'>g/foo/#
The '<,'> range is inserted automatically.
See :help range and :help :g.
I think this might be what you are looking for:
Limiting search scope for code in Vim
Using /\%Vsearch pattern should get you what you want after you have selected the block of code you wish to search in. You enter visual mode by hitting v and moving the cursor around to highlight the block you are searching in.
The almost exact same question has been asked last week on vi.SE.
While \%V can restrict the search to the current visually selected text (which is the precise answer to your question, but not to your indirectly expressed need), selecting the current function is much more tricky than a simple vi{. A perfect and simple way to select the current function requires scripting. That's where my answer on vi.SE kicks in.

Very often while coding, I need to search for keywords which are common and happen throughout a large file, but I am looking for an instance within a function.
The default search functionality often gives me all results starting from the top. Is there any way/workflow to search only within a specific method/function or block of code?
Update
Do Ctrl + F
Then Ctrl + Alt + E
Type the text to search
On MacOS, it's cmd instead of Ctrl

You can do it like this (mentioned keymaps are for Linux):
Let's take as an example the following code, where we will be searching for the word "key" inside the method "clear". As you can see there are many occurrences of that word (in red, highlighted the ones we want in our results, and in blue other occurrences, which we do not want to appear in our search results)
1- Select the area you want to limit the search scope to.
2- Press Ctrl+Shift+F. It will pop up a search window with the selected text pre-filled in the search box.
3- Select the options "Scope" and, in the combo next to it, "Selection" (if they are not selected by default)
4- Type the word(s) you want to search (in this example, the key word).
5- The results shown will be limited to the selected area. Notice how there are only 9 matches in the upper right corner ("Match case" option is checked), despite in the same file there are many other occurrences of the same word.
However, I was neither able to find a key combination in order to do this as a single action nor assign a new one. Also, notice how the search includes the text in the method documentation.
Tested using IntelliJ IDEA 2018.1.4 (Ultimate Edition), Build #IU-181.5087.20 on Ubuntu 18.04
Looks like we're finally getting this feature in IDEA 2019.3:
https://blog.jetbrains.com/idea/2019/09/whats-new-in-intellij-idea-2019-3-eap-2/ (Ctrl-F for subtitle "Ability to search in a selected area when using the Find action")
It’s now possible to search only in a selected area using the Find action (cmd+F / Ctrl +F). Simply select the code piece you need in the editor and invoke the Find action and the IDE will perform the search only in the selected area.
Screenshot from the article (was a GIF originally)
There is a way to search inside a method, however, it doesn't seem to work for other scopes.
When searching in file as usual, click "Find all"
You'll get a list of results in the bottom panel. If you enable "Group by file structure" (I had it disabled by default), you can get a list of matches for a particular method.
On IntelliJ in Mac:
In a file select the specific block in which we want to find
something
Press CMD + F
Press CTRL + OPTION + G
Notice that the cursor has automatically landed in the find toolbar's text field
Type in what is intended to be found
Press enter to move the cursor
to the first occurrence.
Is there a shortcut (or some other quick way) which could restore previous highlighted items quickly, like the one highlighted by / when hlsearch is on?
EDIT: for previous highlighted word, I mean the word highlighted by previous searches via /. 2 search commands with different words are involved here at least.
Vim saves previous searches in the search history. You can recall previous searches by pressing ↑ in the search command-line (which you enter via /). This even considers the typed prefix, so with /foo<Up>, you'll recall previous searches that started with foo.
Alternatively, you can enter the command-line window for searches with q/. There, you can use the default Vim commands to navigate, move around, and edit, and finally select an entry to search for via Enter.
gv re-selects the last visual selection
gn selects the next search match
I'm trying to find a way to make Google Spreadsheet wrap a link, and showing the content in many lines, just like microsoft excel works:
I've found nothing so far on how to implement this, which should be used very often I believe.
Here's how the same excel works imported to Google Spreadsheet:
In the google spreadsheet I selected "Wrap text" but it only wraps it, hiding the overflow of it, however I can't see the whole link.
Any help is greately appreciated.
If you don't mind modifying the contents of the cell in order to display wrapped text, you could use an additional column with a formula like this to insert spaces after certain characters so that the url can wrap:
=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(B1,"&","& "),"/","/ "),"?","? "),"#","# ")
You should keep the original URL around though, since the resulting value will no longer be a valid URL.
Google Spreadsheets only wraps text where there is white space or hyphens. It will not wrap in the middle of a word the way Excel does. There's no way around this I'm afraid.
Below is a screenshot of me entering visual block mode and pressing "w" to select by word:
How can I select every word in the rows I have selected? Meaning I want the full word in the rows highlighted instead of it getting cut off as shown in the screenshot.
edit: What I want to be able to do is delete a column of words of varying length. In the example screenshot I want to delete the words between the tags, But it could be any column of words.
There are a bunch of plugins for multiple selection, look them up on vim.org.
But I must remind you that visually selecting text is more often than not an unnecessary step. Why don't you explain what you actually want to achieve instead of your failed attempts? Maybe there's a better way...
[edit]
:'<,'>norm dit
seems to be the simplest way to achieve your goal without selecting every word:
and :,+7norm dit would be even better because you don't select anything.
The highlight modes can only select blocks (by cursor, by line, or by rectangular block). You can use a plugin such as vim-multiple-cursors to do what you are trying to do.
The only place where Vim allows a non-rectangular, "jagged edge" visual selection is at the end of the lines, i.e. by extending the blockwise selection with $. Therefore, you'd need to (temporarily) get rid of the trailing </th> (or include it in the selection, but operate in such a way that they are kept intact).
You shouldn't need a selection to work with the text. For example, to delete the text inside the tags, you can use a substitution:
:%s#<th>\zs.*\ze</th>##
You can't. You can only select rectangular blocks in block select mode. Maybe a plugin solves this?
What is the best way replace multiple lines with the contents of the clipboard?
The problem I'm having is when I yank a line and paste it over another line the "yank" is replaced with the line I just replace. Now, if I want to replace another line with the same line I have to go back up and yank it again.
There's got to be a better way to do this.
I have this in my .vimrc:
xnoremap p pgvy
(note: this will work only with the default register, but this mapping is easy to remember). Writing a more elaborate version would be possible. Also, you still can use P to get the old behaviour.
"0 should have the contents of your yank. It's a bit more tedious to type, but "0p should do what you want.
Alternatively, don't select-and-replace the old lines up front. If you find those lines with a search, just hit n. over and over (after an initial p), then when they're all pasted, do ndd followed by as many n.s as necessary.
The biggest mental switch I've needed to make when moving to Vim is to figure out how to apply group edits sequentially. I.e. rather than doing a bunch of edits on a line and then doing a bunch of the same edits on another line, I'll do the first edit on a bunch of lines (using . to great effect), then the second edit on a bunch of lines, etc. Alternatively, the use of macros may help as they are fantastic, but sometimes a little more tedious to get working correctly with "complex" changes.
I often use another registry, copy the line you need to some named registry "ay and then paste from there "ap
When you paste over a selection in Vim it will replace the default register with the contents of the selection. If pasting over a selection is wiping out the contents of the clipboard register then very likely you have the following line in your .vimrc
set clipboard=unnamed
One option is to remove that and use the explicit clipboard register "+
Another option is to use any of the other explicitly named registers (a-z). After the first paste yank the line back into "c for example and then use "cp to paste from there on out.
Instead of using copy/paste, it is often better to use a text object command such as ciw to change the inner word. This method has the advantage of being easily repeatable using the . repeat command.
yiw Yank inner word (copy word under cursor, say "first").
... Move the cursor to another word (say "second").
ciw<C-r>0 Change "second", replacing it with "first" ( is Ctrl-R).
... Move the cursor to another word (say "third").
. Change "third", replacing it with "first".
use np where n is the number of how much time you want to paste the lines eg 3p will paste 3 lines.
