[RWP] Cockos Wiki Selecting items, may help with selecting trax?

Sun Oct 7 10:24:15 EDT 2012

you can query Reaper's API to say which tracks are selected and which items 
on each track; at least with Reaper 4 , not sure about 3 though.

>> experiment knowing that your original recorded files are safe.
>>
>> Selecting Items
>> ▪Select an Item by Left-Clicking on the Item. The color of the Item will 
>> change to indicate it has been selected.
>> ▪Select multiple Items by using [Ctrl]+Left-Click.
>> ▪Select adjacent Items by using [Shft]+Left-Click.
>> ▪Select groups of Items by holding down the Alt key, then right-clicking 
>> and dragging a marquee around the Items: [Alt]+Right-Click & Drag.
>> ▪Toggle the selection status of multiple Items by holding down the Alt 
>> and Ctrl keys, then right-clicking and dragging a marquee around the 
>> Items: [Ctrl]+[Alt]+Right-Click & Drag.
>> Split Items
>> ▪If no Item is selected, pressing S will split all Items on all Tracks at 
>> the Edit Cursor position.
>> ▪If Item(s) are selected, pressing S will split all selected Item(s) at 
>> the Edit Cursor position.
>>
>> Copy Items
>> There are several ways to copy Item/s in REAPER
>> ▪Use Keyboard Shortcut Ctrl+C to copy any selected Items
>> ▪Right-click on an item and select Copy selected items from the menu
>> ▪Select an item, then select Edit > Copy selected items
>> ▪Hold down the Ctrl key while dragging the Item(s)
>>
>> Paste Items
>> There are several ways to paste Item/s in REAPER
>> ▪Use Keyboard Shortcut Ctrl+V to paste an Item at the current cursor 
>> position. If a Track is selected, the Item will be pasted into the 
>> selected Track. If no Track is selected, the Item will be pasted into the 
>> last selected Track.
>> ▪Right-click on a Track and select Paste from the menu. If a Track is 
>> selected, the Item will be pasted into the selected Track. If no Track is 
>> selected, the Item will be pasted into the last selected Track.
>> ▪Select Edit > Paste. If a Track is selected, the Item will be pasted 
>> into the selected Track. If no Track is selected, the Item will be pasted 
>> into the last selected Track.
>>
>> Cut Item
>> Cut removes the Item to the Clipboard. There are several ways to Cut 
>> Items.
>> ▪Use Keyboard Shortcut Ctrl+X to cut selected Item/s.
>> ▪Right-click on a selected Item and select Cut selected items from the 
>> menu.
>> ▪Select Edit > Cut selected items.
>>
>> Delete Item
>> Delete completely removes the Item from the project. There are several 
>> ways to Delete Items.
>> ▪Use the Delete key to delete selected Item/s.
>> ▪Right-click on a selected Item and select Remove selected items. This 
>> will delete any selected Items.
>> ▪Select Edit > Remove selected items.
>> NOTE: All selected items will be affected by these processes. The 
>> original items will remain, however, as Reaper is non-destructive. It is 
>> most important to remain aware of what you have selected or unintended 
>> consequences will follow e.g. deleting more items from the project than 
>> what you intended to delete.
>>
>> Looping an Item
>> All Items except Empty Items can be Looped. The Loop point is defined by 
>> the duration of the source Media. If you insert an Item that is four bars 
>> long, it will Loop every 4 bars, if it is 8 bars, it will loop every 8 
>> bars, and so on.
>> To Loop an Item:
>> 1.Mouse over an edge of the Item until the Cursor changes to a 
>> double-headed arrow.
>> 2.Drag the Cursor to extend the Item. Each Loop Point will be indicated 
>> by a notch in the edges of the Item.
>> 3.Extend the Loop as required.
>> The length and play rate of the Looped Item will be displayed as you drag 
>> the edge of the Loop.
>>
>> Fade In
>> A Fade In raises the output volume of an Item from 0dB at the start of 
>> the Fade In up to the Fader Volume of the Track at the end of the Fade 
>> In.
>> To create a Fade In:
>> 1.Mouse over the starting edge of the Item until the cursor changes to a 
>> Fade Cursor.
>> 2.Drag the edge of the Item to the right to create the Fade In. The 
>> duration of the Fade In you are creating will be shown to the right of 
>> the Cursor as you drag the edge of the Item.
>> 3.Release the mouse to complete the Fade In.
>> You can also set a Fade In duration through the Media Item Properties 
>> window.
>>
>> Fade Out
>> A Fade Out lowers the output volume of an Item from the Fader Volume of 
>> the Track at the beginning of the Fade Out down to 0dB at the end of the 
>> Fade Out.
>> To create a Fade Out:
>> 1.Mouse over the edge at the end of the Item until the cursor changes to 
>> a Fade Cursor.
>> 2.Drag the edge of the Item to the left to create the Fade Out. The 
>> duration of the Fade Out you are creating will be shown to the right of 
>> the Cursor as you drag the edge of the Item.
>> 3.Release the mouse to complete the Fade Out.
>> You can also set a Fade Out duration through the Media Item Properties 
>> window.
>>
>> Volume
>> Item Volume is independent of Track volume. Item Volume can be set per 
>> Item, or for multiple selected Items by adjusting one of the selected 
>> Items.
>> To set Item Volume:
>> 1.Mouse over the top edge of the Item until the cursor changes to a 
>> vertical double-headed arrow.
>> 2.Drag the cursor to lower the Item Volume. The Item Volume will be shown 
>> to the right of the Cursor and the Peaks will be redrawn to reflect the 
>> change in Peak Volume as you drag the edge of the Item.
>> 3.Release the mouse to complete the change in Item Volume.
>> By default, you cannot drag the Item Volume above 0db. This behavior can 
>> be overridden by pressing the SHIFT key while changing the Item Volume or 
>> could be permanentely changed in the Media preferences dialog to have the 
>> volume range go from -inf to +6dB.
>> You can also set Item Volume and raise it above 0db by using the Volume 
>> Fader in the Media Item Properties window.
>> Item Processing
>> The Item processing sub-menu can be found when you right click on an 
>> event and consists of Normalize Selected Items, Auto trim/Split Selected 
>> Items, Quantize Items Position to Grid and Move items to Source Preferred 
>> Position
>>
>> Normalization of an event in REAPER is non-destructive and is extremely 
>> useful for raising the overall volume of an event without having to touch 
>> the track's volume slider or use an envelope. Normalize will simply raise 
>> the volume of the event so that the highest peak reaches 0dBFS. Keep in 
>> mind that you can still lower the volume of the selected event by using 
>> the item volume adjustment tip above, and that event's peaking at 0dB 
>> will not produce audible digital clip noise unless either the master buss 
>> clips, or a plug-in overloads internally.
>> The Auto Trim/Split function is incredibly flexible and useful for drum 
>> editing when combined with 'quantize item positions to grid'
