I noticed that many people don’t know very useful shortcuts in FlashDevelop. Therefore I listed them below. Many of them can be used in advanced text editors like Notepad++ (edit section and further).

Development shortcuts

Ctrl+SPACE = Autofill.
Ctrl+Alt+SPACE = Autofill with class name.
Ctrl+Shift+SPACE = Shows method parameters hint if cursor is inside method call.
Ctrl+Shift+1 = Template generation. You can generate:

• Getters and setters if you are on field definition.
• Class field if you are on undeclared variable.
• Function if you are on undeclared function.
• Event handler if you are on undeclared event handler.
• All public methods and properties inherited by current class from the interface under cursor

Ctrl+B = Snippet insertion. Snippet is unparameterized code template. In instance, condition or loop. You can add/edit snippets by Tools->General Tools->Snippet Editor…
Ctrl+J = Activating TypeExplorer window. It helps to find the class by the first letters of class name. You can open the class at once.
F5, Ctrl+Enter = Compile project
Ctrl+Shift+K = Insert color
Ctrl+Shift+I = Insert GUID.

F4 = Goto method/class/property declaration.
Shift+F4 = Come back from there
F12 = Goto Next error.
Shift+F12 = Goto Previous error.
Ctrl+[ = Goto next statement (declaration of variables or function, condition statements, new operator etc.)
Ctrl+] = Goto previous statement
Ctrl+Shift+F = Expand/collapse current line

Ctrl+U = converts selected word to uppercase

Ctrl+right arrow = Goto next word

Ctrl+/ = Goto previous subword (separate word or subword starting with capital letter. For example, the subword “Count” in word “filesCount”)
Ctrl+\ = Goto next subword
Alt+Home = Goto real line start but not the first not-null symbol of the line like Home key.
Ctrl+Home= Goto file begin.
Ctrl+End = Goto file end.

Windows managements

Ctrl+S = Saves the Tab
Ctrl+Shift+S = Save as…
Ctrl+W = Close the current tab

Hold CTRL and pressing TAB several times = switching tabs in forward direction
Hold Ctrl+Shift and pressing TAB = switching tabs in backward direction
Ctrl+TAB = Goto last active tab
Ctrl+PgUP = Goto between tabs from right to left

I hope this shortcut list will help you use FlashDevelop more efficiently.
