MS Word using columns

Try Tab.

Just keep typing in column 1
or keep pressing return.

Columns flow into each other - they are not distinct like table cells.

Ctrl+Shift+Enter
Or
TAB key from keyboard.

I didn't know that Ramin!

Tab key works between tables but Ctrl+Shift+Enter works between columns.

None of those solutions work.
I am assuming I have 3 columns and not tabs.
To continue to type and then use the space bar or enter key as the "return" gets nowhere. As far as going from the bottom of column one (page 2) to the top of column two (page 2). Enter moves the cursor to the top of column one on the next page which is page three and currently empty.
Tab = highlighted everything in column two but it was on page 1. All three columns of page one are full of text.
I'm working on page 2 and near the bottom of column 1.
Control-Shift-Enter moved the cursor from the bottom of column 1 on page 2 all the way to the top of a new window with no columns and this page was above page 1. So it created a new page above the work sheet I have.
In a previous question long ago the answer was posted by "P". I'll go search for it.

Did you try Alt + Page Down ?

Alt gets the cursor to move from the bottom of column 1 on page 2 to the top of column 1 page 3. See yellow arrow.
I want to go bottom column page 2 to top of column 2 on page 2. Red arrow.

How about Alt + right arrow ?

Alt by itself or right arrow by itself or both at the same time get nothing or get the same thing you see by the yellow arrow.

I think Alt + Down Arrow will work if you put some text (it must not be empty) on column which you want the cursor to go there.

you can double click the mouse on the beginning of column2 and put some text and try Alt+Down.

Sorry, what I have are 3 tables. So the question changes for you and Eirman to comment with a solution.

Tab key on keyboard must work.

So you have a 3 column table - use TAB to to go to the next column
Shift + TAB to go to the previous column

I've already tried the Tab key and it does not work. Shift and then Tab left or right, or Shift - Tab at the same time do not work.

I do not have columns. I have "3 tables."

I know the answer but allow time for someone to post it.

TRY CTRL+pgdown or CTRL+Arowdown .
TRY ALT+pgdown or ALT+Arrowdown.

Tab also works on my PC.

I do have Office 2007.
F5 from that link did work.
Here is the method that was the solution for another question here on EE that I posted many months ago.

Click on the symbol you see at the end of the arrow. That symbol then appears at the end of all lines. Put the cursor inside the top of the 2nd column and then click on that symbol at the top and they all disappear and I can begin text in column 2 (rather table 2)

thanks
