Sharepoint 2013 - Remove [2] from webpart Title - sharepoint

My Home page with all the webparts has a number in brackets after the webpart title.
How can I remove this?

Ok, I found a solution.
Stay at the page that you can see "XXX [Number]"
Click the "Page" button at the top-left corner
Click the "Edit Properties" button
Click the text(possibly blue) "Open Web Part Page in maintenance view"
Check the duplicate web parts you want to remove and click the "delete" button above.
(If you are NOT sure which are the web parts you want to keep, please delete them all and re-add the web parts you need. Otherwise, you might end up with some white space on the web part page.)

The number gets added because you have multiple web parts configured with the same title. You need some change on the webpart's title to make the [2] disappear.
Alternatively, you might want to hide the webpart's title. Edit your webpart, expand the "Appearance" section, and select the option "None" on the "Chrome type" dropdown.

This was driving me nuts too. Follow the steps here for the steps to delete it through the webpart maintenance page:

Add a space after the title, this way you can use the same title for multiple webparts.

Of course you should delete the "extra" duplicate web parts using the same title if they aren't visible on the page. But it's not unusual to want the same title showing for different web parts. In that scenario, a simple fix is to add a space after the title in the Appearance section of the duplicate web part's properties. If there are multiple web parts with the same title, just add more spaces. SP will treat the titles as unique.

How to implement scroll to a section/fragment on click in Liferay?

I want to implement scrolling to a particular section on click in Liferay, but I have no idea how to add functionalities in Liferay.
I have created a page using multiple fragments and in the top of the page I have headers of the sections and on click of a header the page should be scrolled to that particular section.
Attached page screenshot link below for reference
The easiest way to scroll to some place on the page is to place an anchor there, e.g. with <a name="scrollTarget"/>. In your navigation, you'll just link to this by Scroll to Target and you're set.
Of course, this can be done a lot fancier, with an animated scroll etc, but the basic start is this. There's nothing Liferay-specific hidden here - pick any of the more fancy methods, create fragments with the proper markup, and make sure they're used on your page.

Netsuite: Any way to hide the center tab which seems like a customize tab

How to remove or hide the center tab? It seems to me like a customized tab. I tried to look into Customization> Center and Tabs > Center Tabs but no luck. I search through all the scripts deployment but do not see any related. They are just lying on the bar there permanently. Any help is appreciated.
Hover on the custom tab you want to remove, say "Intranet", and the first entry in the drop-down should be the tab overview section - in this example "Intranet Overview". Click that and look for "Edit Custom Tab" near the top right. Click that and under Audience you can remove the role from the tab.
You can also get to the edit tab screen through Customization > Centers and Tabs > Center Tabs as you were, but you need to make sure you're looking at the tab under the correct Center you're using in the role you want to remove it for, and then under the Audience tab you choose which Roles (or employees, groups or whatever) it will show for.
Finally I managed to hide these two annoying tabs from the bar. :)
You just have to navigated to Setup > Company > Enable Features and then under Web Presence Tab and uncheck the Intranet box as shown in below. Done.

How to create a user-impaired accessible website: surfing without a mouse?

I have created a webpage using Backbone.js and Marionette.js that mostly consists of a bootstrap accordion view that displays a list of items when the accordion header is clicked. Each item can also be clicked, which will show a hidden div of detailed information that pertains to that particular item.
I would like to make this site accessible to people who might not be using a mouse (Maybe they're visually impaired and using a screen reader? Maybe they just don't like clicking things? Either way.) I'm thinking that this would mean being able to press the Tab key to get to the accordion, pressing Space or Enter to open the accordion, Tabbing down (or down arrow key?) through the list items, and then using Space or Enter to show the selected item's hidden div.
I'm finding it difficult to find information on how to add a feature like this, since searches like "How to make an accessible website that can be used without a mouse" mostly turns up blogs on what a developer should do to add accessibility to a page, and not much on how to do it.
Currently, the page doesn't really respond to any keyboard buttons. Any tips or resources you could share would be extremely appreciated. I've been fiddling with ARIA role tags, but I'm either not doing it right or it's not the answer here.
You have to use tabindex

Screen readers automatically read whatever element is the activeElement

How to remove whole Site Actions menu for specific users?

I have been doing research, and I havent found a way to remove the WHOLE site actions menu for "non-content editors" in sharepoint. I have researched this:
<SharePoint:SPSecurityTrimmedControl ID="SPSecurityTrimmedControl2" runat="server" PermissionsString="ManageSubwebs">
but this only hides certain links in the site actions menu, what if I want to hide the whole thing so you cant even see 'site actions' in the upper left hand corner of the page for certain users. The content editors should be able to see this menu, but non-content editors should not be able to see this menu at all.
Try changing PermissionsString to "ManageWeb"... it will hide for all users who doesn't have ManageWeb role... How are you going to categorize "certain users" in your question, if it is by role, you can quickly have a look at msdn
i know its a bit of a cheat way round, but i used this from codeplex... you can sepecify what users see it through groups http://spribbonvisibility.codeplex.com/
the only issue is it does remove the users name from top right, and leaves no menu there...

SharePoint 2007 navigation and removing its delay

In SharePoint 2007, there's a top nav that the user can hover over, which reveals a dropdown menu of subitems. When they remove their mouse from the dropdown, it disappears, but only after a short delay. This can cause problems, as if people are trying to click a link on the page somewhere, but the nav menu hasn't hidden itself yet, they'll accidentally click it instead. This is compounded with the fact that the menu appearing in the first place is delayed as well, so right before they mouse over the link on the page they actually want to click, the menu will suddenly appear and intercept their click when they weren't meaning to.
I've poked at core.js at some suspect areas, but can't seem to nail it down. Any thoughts?
This is the normal behaviour of SharePoint. This control is the asp:Menu control of ASP.Net 2.0 and the only thing you can do is customized the MasterPage or the DefaultPage of your Site.
If you change the core.js file of "layouts" folder you'll lose Microsoft support, so take care about change any of the file from this folder.
I recommend that you modify the existent control or create a new one and put it in this position of the MasterPage.
This bit of CSS will fix it. I just had the same thing in sharepoint 2010 and this was all that was required to make the list disappear as soon as you roll off:
li.hover-off>ul
{
display:none;
}
The way it works is when you hover over an item in the nav it adds a css class called "hover" and as soon as your mouse leaves the area it changes the class to "hover-off" for 1 second before removing it completely. This CSS will hide the unordered list directly below the list item that has the class "hover-off" thus hiding the flyout as soon as your mouse leaves the parent.
